Update errors

Problem Description

As a developer, it would be helpful to have more descriptive error types, so that different types of crashes could be handled separately.

Expected behavior

• Remove the Error class and replace all instances with the appropriate of the following. Add the new error type if not already created.
  • InvalidConfigError: Something is incorrect about the config. Use in any method that sets or updates the config:
    • column names in 'transformers' are different than 'sdtypes'
    • incorrect 'sdtypes'
    • incorrect transformer names
  • InvalidDataError: The data is ill-formed in some way. Use any time data is passed in and doesn't match the expected format
    • data in fit doesn't match config
    • data in transform doesn't match config
    • data in reverse_transform doesn't have the right columns"
  • TransformerNotFitError: Trying to use the HyperTransformer before fitting it
    • Transform (transform_subset) before fit
    • Reverse transform (reverse_transform_subset) before fit
    • create_anonymized_columns before fit
  • TransformerInputError: The input to the hypertransformer is incorrect
    • assigned transformer doesn't match the sdtype
  • TransformerProcessingError: Catch all for anything that doesn't fit into the above. NOTE - Only add this one if needed.
