Deep-FRET Release for M1 macs

This binary has been designed specifically for M1 macs. The biggest difference is tensorflow for M1 macs requiring python 3.8 instead of 3.6. This, along with also using the latest versions of many packages, required some light refactoring of the code. More details are available in Adaptations_for_M1.md under the Mac-m1 branch or v3.0.0-M1 tag.
