Add support in @theia/ffmpeg replace-ffmpeg.js to specify required platform and arch

[RobMoloneyPILZIE]

In the electron module install.js file there is code to specify 'platform' and 'arch' values.
const platform = process.env.npm_config_platform || process.platform;
let arch = process.env.npm_config_arch || process.arch;
This helps the developer to do cross platfrom builds on one OS.

Could we change the replace-ffmpeg.js file in @theia/ffmpeg to something similar e.g.

if (shouldDownload) {
const platform = process.env.npm_config_platform || process.platform;
let arch = process.env.npm_config_arch || process.arch;
const ffmpegZipPath = await electronGet.downloadArtifact({
version: electronVersion,
artifactName: 'ffmpeg',
platform: platform,
arch: arch,

Hey @RobMoloneyPILZIE, this sounds like a feature request. Mind filing an issue for it instead? (discussions are not actionable, and the Improvements category is used mainly for discussion on an architectural level).

Thanks for the reply Mark. No problem. I'll create an issue instead.
