Added support for custom field mappings (#664)

* Added the ability to set & map custom fields, using a new CMDT LoggerFieldMapping__mdt and new LogEntryEventBuilder instance method overloads setField(Schema.SObjectField field, Object fieldValue) and 
setField(Map<Schema.SObjectField, Object> fieldToValue)

* Added some CMDT records to the extra-tests directory that map the included custom fields (also stored in the extra-tests directory). These CMDT records are just to help with functionally/manually testing in a scratch org - they won't be included in any of the packages

* Scope creep: Updated several config classes to consistently have test-visible private methods before non-test-visible private methods

* Updated README.md to add details about custom field mappings, and cleaned up/updated some other README contents

* Added .github/FUNDING.yml so the repo has a sponsor button

+## Adding Custom Fields to Nebula Logger's Data Model
+
+As of `v4.13.14`, Nebula Logger supports defining, setting, and mapping custom fields within Nebula Logger's data model. This is helpful in orgs that want to extend Nebula Logger's included data model by creating their own org/project-specific fields.
+
+This feature requires that you populate your custom fields yourself, and is only available in Apex currently. The plan is to add in a future release the ability to also set custom fields via JavaScript & Flow.
+
+### Adding Custom Fields to the Platform Event `LogEntryEvent__e`
+
+The first step is to add a field to the platform event `LogEntryEvent__e`
+
+- Create a custom field on `LogEntryEvent__e`. Any data type supported by platform events can be used.
+
+ - In this example, a custom text field called `SomeCustomField__c` has been added:
+
+ ![Custom Field on LogEntryEvent__e](./images/custom-field-log-entry-event.png)
+
+- Populate your field(s) in Apex by calling the instance method overloads `LogEntryEventBuilder.setField(Schema.SObjectField field, Object fieldValue)` or `LogEntryEventBuilder.setField(Map<Schema.SObjectField, Object> fieldToValue)`
+
+ ```apex
+ Logger.info('hello, world')
+ // Set a single field
+ .setField(LogEntryEvent__e.SomeCustomTextField__c, 'some text value')
+ // Set multiple fields
+ .setFields(new Map<Schema.SObjectField, Object>{
+ LogEntryEvent__e.AnotherCustomTextField__c => 'another text value',
+ LogEntryEvent__e.SomeCustomDatetimeField__c => System.now()
+ });
+ ```
+
+### Adding Custom Fields to the Custom Objects `Log__c`, `LogEntry__c`, and `LoggerScenario__c`
+
+If you want to store the data in one of Nebula Logger's custom objects, you can follow the above steps, and also...
+
+- Create an equivalent custom field on one of Nebula Logger's custom objects - right now, only `Log__c`, `LogEntry__c`, and `LoggerScenario__c` are supported.
+
+ - In this example, a custom text field _also_ called `SomeCustomField__c` has been added to `Log__c` object - this will be used to store the value of the field `LogEntryEvent__e.SomeCustomField__c`:
+
+ ![Custom Field on LogEntryEvent__e](./images/custom-field-log.png)
+
+- Create a record in the new CMDT `LoggerFieldMapping__mdt` to map the `LogEntryEvent__e` custom field to the custom object's custom field, shown below. Nebula Logger will automatically populate the custom object's target field with the value of the source `LogEntryEvent__e` field.
+
+ - In this example, a custom text field called `SomeCustomField__c` has been added to both `LogEntryEvent__e` and `Log__c`.
