Describe the feature or the problem it solves
As a user I want to start a timer for the selected long exposure, instead of remembering the value and setting it manually in an external timer app.
Describe the solution you'd like
[x] Exposures >= 1" must be tappable
[x] Add "Start timer automatically" to the settings, default is true
[x] By tap on long exposure open the timer screen and start the timer according to the settings
[x] Camera should be released the same way as when settings screen is opened
[x] User should be able to start/stop and reset the timer
[x] User should see the selected exposure pair at the top of the screen and current ISO/ND values
[x] Add golden test for timer screen
