bug(medcat): CU-869banbwt Fix issues with installation from source by providing providing package directory

[mart-r]

There were previously issues with installing from source. Specifically, it happened in the following scenario:

• The project had previously been built
  • The build folder exists within the medcat-v2 folder
• The current state of the project is older than the latest build time
• The above meant that setuptools considered the build up to date
  • Because the current soruce was older than the build state
  • And the version of the project was still the same

In order to fix this, we needed to introduce a local versioning scheme. However, in order to do that, we needed to make quite a few changes. Here's the list of things this PR changes:

• Specify tool.setuptools.package-dir in pyproject.toml
  • This will fix issues with installation when there's other folders in the root of the project
  • Which can happen (e.g) after tests which create a results folder
• Add setuptools_scm to build system
  • So the below can be done
• Make version dynamic
  • Version is now read based on tag that's been used
  • This is standard practice
• Give the version tagging system a regular expression
  • The default is expecting tags like v2.3.4
  • But due to us having multiple repositories we have prefixes
  • So the regex needs to account for that
• Use correct root target for setuptools_scm
  • Need to use the parent folder
  • That's where the .git folder with the relevant tags is
  • Otherwise setuptools_scm would be unable to find the tags and thus the version
• Use a local versioning scheme
  • So that locally built versions have a useful version
  • And so that it changes on a per commit basis
• Mark the project as being in stage 5
  • I.e production instead of beta
• Merge in the v2.4 branch
  • So that the tag appears in history
  • Otherwise they are unable to be discovered
• Change the release scripts
  • To account for changes
  • Now creating tag on main branc
  • Not doing any git add / commit
  • And branching from there for release branch
