MacOS support and EVF Zoom

[RedSparrowEU]

Hi,

First of all - great job! The code is like a work of art. Outstanding! On Windows, compilation and installation was a pleasure. So rarely I have had the opportunity to observe so silky smooth process. The examples show that everything works as it should. Camera connects, taking pictures, processing live view... I also tried on MacOS (10.14 and 10.15). Well, and again - even this platform was considered as a target - great! The installation process was less smooth and required a few extra steps, but it worked! However, during startup, the program got stuck, I presume, on linking EDSDK framework or init process.... hard to say more... in any case, the question is, did you successfully use the MacOS version of your libs? Second question, are you planning to add EVF zoom data (rectangle/position)?

Used tech: Build - Node 16.15.0 (win) / 16.14.2 (mac), Runtime - Electron 20.0.2

Thanks again! Greg
