Add support for X1 Boost (FW Version 3) (continued)

[rnauber]

Hi there, this PR builds on PR #128 from @martijnvdmolen to support FW v3 of the X1 Boost inverter. It fixes some merge conflicts, is up to date with the current master and resolves a mismatch in the type field. And it was tested successfully!

Thank you for your amazing work @martijnvdmolen and @squishykid ! Best Richard

Hi @squishykid , I updated the PR as I saw some fields have a different meaning on the x1_boost vs x1_boost_g4. Now it is working flawlessly and I think the PR is ready to merge.

Best, Richard

Looks great, sounds like we can also close #128
