[kwabenantim]

Description

• Support Python 3.12 and 3.13
• Drop support for Python 3.6 to 3.8

Motivation and Context

Closes #374

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Documentation checklist

• I have updated all documentation in the code where necessary.
• I have checked spelling in all (new) comments and documentation.
• I have added a note to RELEASE.md if relevant (new feature, breaking change, or notable bug fix).

Testing

• Testing is done automatically and codecov shows test coverage
• This cannot be tested automatically

@MichaelClerx does a release 0.4.0 sound sensible?

I've made it version 0.3.7 in line with previous changes for Python version support.

Are you happy for this to go in with the new commits @MichaelClerx ?
