Add test cases and handle exceptions for undefined rules (#61)

Added additional tests for when schema file not found and when certain
rules are left undefined. These tests cover cases for allowed values,
date formats, disallowed values, and regex pattern. Furthermore, a new
rule for checking whether a cell data is trimmed was introduced. Also
fixed some formatting errors and updated the README file.
