[FEATURE] Perform Data Analytics on Output Generated JSON intel#8

Analysing JSON data from 2 different ROM images in the form of Pie chart and bar graph view of various parameters.

This implementation allows us to see comparative analysis of 2 binary files. With the help of pie chart and bar graphs, we can analyze various components of section types and file types.

+# Analysing JSON data from 2 different ROM images
+
+## Pie chart and bar graph view of various parameters from 2 JSON files 
+
+Following types of views can be seen - 
+
+1. Pie chart view of both the images based on file type and section type
+2. Bar graph view of each of the parameters of file type and section type to see the comparison in both ROM images
+
+Installation of ```matplotlib``` is a prerequisite.
+
+```python
+python -m pip install matplotlib
+```
+
+
+## Seeing Pie charts from 2 different JSON files 
+
+Taking 2 JSON files output_1.json and output_2.json as example, we can see the pie chart representation of each of the file types in the following way -
+
+```python
+python analytics.py output_1.json output_2.json filetype
+```
+
+Similarly, we can see pie chart representation of each of the section types in the following way -
+
+```python
+python analytics.py output_1.json output_2.json section
+```

+
+## Seeing Bar graph of various parameters in 2 different JSON files
+
+if we want to compare the count of FV_FILETYPE_DRIVER, we can do it in the following way -
+
+```python
+python analytics.py output_1.json output_2.json filetype FV_FILETYPE_DRIVER
+```
+In the same way, we can compare the count of any section or file type in the 2 JSON files.
+
+We can compare the count of EFI_SECTION_COMPRESSION in the following way -
+
+```python
+python analytics.py output_1.json output_2.json section EFI_SECTION_COMPRESSION
+```
+
+Currently, the following file types and section types can be seen in the form of bar graph -
+
+```python
+	python analytics.py output_1.json output_2.json filetype FV_FILETYPE_DRIVER
+    python analytics.py output_1.json output_2.json filetype FV_FILETYPE_APPLICATION
+    python analytics.py output_1.json output_2.json filetype FV_FILETYPE_FREEFORM
+    python analytics.py output_1.json output_2.json filetype FV_FILETYPE_PEIM
+    python analytics.py output_1.json output_2.json filetype FV_FILETYPE_SMM
+    python analytics.py output_1.json output_2.json filetype FV_FILETYPE_FIRMWARE_VOLUME_IMAGE
+    python analytics.py output_1.json output_2.json filetype FV_FILETYPE_RAW
+
+    python analytics.py output_1.json output_2.json section EFI_SECTION_COMPRESSION
+    python analytics.py output_1.json output_2.json section EFI_SECTION_FIRMWARE_VOLUME_IMAGE
+    python analytics.py output_1.json output_2.json section EFI_SECTION_PEI_DEPEX
+    python analytics.py output_1.json output_2.json section EFI_SECTION_DXE_DEPEX 
+    python analytics.py output_1.json output_2.json section EFI_SECTION_PE32
+    python analytics.py output_1.json output_2.json section EFI_SECTION_RAW
+```
