Improve unzip time on Windows

See original GitHub issue

Current behavior:

Windows uses a Node.js-based method to unzip the Cypress binary during cypress install, which is fairly slow.

Desired behavior:

Windows uses some faster method, like the native win32 zip APIs, to unzip the Cypress binary during cypress install, only falling back to the Node.js unzip method if the faster method fails.

this issue is still there. no caching helps - node modules are cached ($(Pipeline.Workspace)\s\e2e\node_modules), cypress binaries are cached from the cypress cache folder (C:\Users\VssAdministrator\AppData\Local\Cypress\Cache). But npm ci still tries to install cypress which is nothing but cypress for me and it takes long - 25l[19:57:59] Downloading Cypress [started] [19:58:02] Downloading Cypress [completed] [19:58:02] Unzipping Cypress [started] [20:02:27] Unzipping Cypress [completed] [20:02:27] Finishing Installation [started] [20:02:27] Finishing Installation [completed] 25h

Is there another faster way to install cypress on my build agent (.NET fwk app on windows and azuredevops for CI) and run tests?

@flotwig Yeah +1, in the interim caching the cypress binary should speed things up.
