[FEAT] Add ability to configure valid git commit types

[Recidvst]

Is your feature request related to a problem? Please describe.
Would it be possible to add an option to provide a config file to set the list of possible valid git commit types? We use a superset of the standard 'Conventional Commits' rules and our extra items throw errors when using tug commit.

Describe the solution you'd like
It would be awesome to be able to read from a config file at a repository level as per Commitlint's approach (example config file). Could commit.go potentially check for a local config file before building up the list of types, and then fall back to the hardcoded list if one isn't available?

I don't know Go at all so apologies if this more difficult than it seems :) Turbogit is awesome btw, thanks! 💯

Hey, thanks for creating the issue. It's not simple in the sense that a lot needs to be refactored in order to be dynamic (mostly this file).
But it's definitely useful. Keeping this in the backlog for a future release.
FYI turbogit is using the same config model (and files) as bare git. The config read is already implemented (and used for example in the new jira integration wip), we just need to make commit type dynamic.

Thanks @b4nst, I'll keep an eye out :)
