Add support for Mac M1 chip

[cpaulgilman]

SAM does not run on new Mac computers with the ARM-based M1 chip.

Solution is to build installation image file to support both older Intel-based and new ARM-based Mac computers.

Mac users are reporting an intermittent crash on macOS (sometimes happens every 3 tries or so):

To replicate:

1. Open SAM.
2. Start new project: Photovoltaic > Detailed PV Model > Distributed > Residential Owner
3. Click Simulate.
4. When the simulation finishes, click Simulate again. SAM crashes.

I frequently receive this graphical bug on my MacBook with the M1 Chip (macOS Big Sir: Version 11.4). When I hover over the black areas, SAM restores the UI.

In our testing as of October 2021, when you install SAM on a Mac with an M1 chip, you are prompted to install Rosetta, which allows apps written for Intel-based chips to run on the M1 chip:

Here is a link to some information about Rosetta from Apple:

This solution should be sufficient for now, so I am closing this issue.
