- Added support for BINTEXT and BOOLEAN for data format version 7
    - BINTEXT is sent and received as buffers
    - BOOLEAN can be sent as strings, numbers, and boolean and received as boolean
- Modified data type integration tests to skip tests when the data format version is lower than required
- Added integration tests for BINTEXT and BOOLEAN
- Added unit tests for BOOLEAN

- Added spatialTypes option to allow strings to be sent for spatial types
    - With spatialTypes=0 (default), strings inputted for ST_GEOMETRY and ST_POINT are interpreted as hex
    - With spatialTypes=1, strings inputted for ST_GEOMETRY and ST_POINT can be encoded in utf8 or cesu8
    - Buffers can be sent in any of these options and will be interpreted as binary
- Added integration tests to check inserting and fetching large ST_GEOMETRY data
- Added some integration tests to check the spatialTypes=1 behaviour

- Changed the Writer to return an error message of 'Argument must be a string or Buffer' when an invalid type is entered for spatial types
- Added some hex string and buffer inputs to ST_POINT tests
- Changed some inputs for integration tests to describe what is tested more accurately

- Merge changes for data format version 5 into this branch to resolve merge conflicts
