redundant M5L5 code

[aaronjfisher]

Hello,

This issue is based on something mentioned here

#305

g.getM5L5 is not called inside of g.part5. Rather, g.part5 seems to have additional code for M5L5. Suggesting to consolidate and use g.getM5L5 throughout, to make it easier to update and/or submit changes to each part.

Thanks!

Thanks, I am a bit busy with other (paid) developments at the moment. Maybe later in the year. That said, pull requests are always welcome.
