install dependencies with gammalauncher installer

[mhusinsky]

when installed on a totally fresh win10 system, gammalauncher does not launch as it lacks some dependencies (probably .net6 runtime).

the easiest way to solve this is to install some vvvv gamma preview (2022.5), because it actually installs all nescessary runtimes to also run the gammalauncher. however, this requires the extra step of going to the webpage and downloading/running the respective installer.

it would be nice if the gammalauncher installer itself would also initiate the install of all required runtimes to run itself, then it could really serve as the single point of entry into the vvvv-world.

Nice suggestion, thanks, also had to manually install the runtime testing the launcher on a fresh machine. Will investigate that!

GammaLauncher is now available as a winget package that also takes care of installing the required vcredist and .NET6.
