configure DFCO MAP threshold to vary based on RPM

Addresses my idea proposed in #478

I did a brief test drive in my car to verify that it works. Feel free to reject if this seems like it would contribute unnecessary bloat to the project.

1. looks like a merge conflict in the TS template
2. I'd love to see a unit test for this new behavior!

On it.
Do you think it would make sense to also add a field to set hysterics for the MAP threshold?

Also, do you think the “ MAP Mode” drop-down selector is needed? Fixed is the same as setting a flat table, but it allows the existing tune settings to work when updating to the new firmware for the first time.

Yes - breaking back compat is sort of unacceptable, so the dropdown is required.
