Remove spark

[MattWellie]

This is a very low priority

Purpose

• To remove Spark/Hail from Talos, I also have to remove Hail/Spark from all the dependencies

Proposed Changes

• Creates a new version of clinvarbitration, removing all hail interactions. VCFs are written manually instead of using HT -> VCF export, and the PM5 Hail Table is replaced with a JSON lookup
• No impact on current versions of Talos, the dependency pin will tolerate all minor version bumps, but this is a a major

Checklist

• Related GitHub Issue created
• Tests covering new change
• Linting checks pass
• Bump the version number with bump2version

dead-code: check_params() is still defined at line 63 of the same file but has no remaining callers after this deletion.
