fix(web): made it work with Capacitor 4

[trancee]

refers to #243 and #247

• cleaned up code a bit
• possible breaking change: added format on Web to choose which picture format should be output
• quality will default to 85% to achieve feature parity with other platforms
• made sure streams are properly handled when opening, capturing and closing camera

please kindly review my changes.

Thanks for your reply,

I checked out this issue.- gh pr checkout 249 and did an npm run build locally, build was successful but showed a number of TS errors. Not sure if I am doing something wrong here? Apologies if so I am a newbie to capacitor (about 2 months)
