feat: Alternative mode for camera (Android only feature)

[g123k]

What

The MLKit plugin doesn't work on some devices with a byte array, but is OK when passing a file instead.
The native plugin (camera) is able to both provide a byte array or a file only on Android (as iOS seems OK).

The PR allows switching between the two modes.

Here is the screenshot of the new setting (only visible on Android)

Some notes:

• The focus should now be a bit quicker than before (my last PR was a bit too conservative)
• For the "normal mode", the native part only sends one image every 100 ms (some devices like the Pixel 6 Pro was able to send 3 images during this time). It should lower memory usage.

An open question: we have a list of whitelisted devices (eg: OnePlus smartphones).
Should we let the choice to change the mode?

• What about a button to relaunch the app (not sure that's even possible ?)
• What about a button to autogenerate an email with the device name ?

Or even log the device name when opening this settings, and using matomo, we should be able to see successful scans

This is a nice idea.
But first I want to be sure it works well.

To be honest I wonder if it shouldn't be the new default mode

Given all the pain in the neck around the camera, if you found a more reliable code I agree that we should use it as the default mode.

The drawback with this new solution is that it consumes more I/O on the storage, but less memory.

Some devices use microSD and in that case, I'm not entirely sure what it can give in terms of performance.

I'm not a big fan of the dynamic typing but thats fine, the code looks fine to me. Lets merge, test and then decide if we change to default mode

[g123k]

That's idea here, a first implementation to test if the scanner works better and I will create a second PR to improve things accordingly 👍

ok, merging
