Add support for browser launch timeout #96

Closed jsuchal closed 10 months ago

jsuchal commented 10 months ago

For slow hardware (e.g. home assistant running on old Raspberry Pi) the headless browser launch timeouts with error (see below).

This adds and ENV option to override the default 30s limit.

I was unable to test this on the raspberry, but I was able to replicate the behaviour on my machine by setting a very low limit (e.g. 30ms).

Not sure if I found all places where this config should be exposed, but building locally this works.
