Change BLOB fields to LONGBLOB in DecodingParameters (LorenFrankLab#1463)

* Change BLOB fields to LONGBLOB in DecodingParameters

Updated the 'decoding_params' and 'decoding_kwargs' fields from BLOB to LONGBLOB in the DecodingParameters table definition to support larger data storage for model initialization parameters and keyword arguments.

* Update changelog for DecodingParameters changes

Added a code example using DecodingParameters.alter() and documented the change from BLOB to LONGBLOB fields in DecodingParameters (LorenFrankLab#1463).
