feat: Scanner improvements

[g123k]

This PR contains several improvements for the scanner:

• Move the decoding part in an Isolate
• Improve the MLKit algorithm by limiting the types of supported barcodes
• "Adaptive algorithm" to start the decoding (cf below for more details)
• Ask for a camera lower resolution (high -> medium)
• [UX] When a barcode is scanned, a small vibration notifies the user

"Adaptive algorithm" :

• The duration of each decoding is now stored.
• An average value of the last 10 decodings is computed.
• The average time (what I call a window) is then multiplied by 10 (this value is arbitrary, we can change it)
• This sum is then used as the time between two decodings

What's still missing: pause the barcode when scrolling between the carousel's cards.
-> Will be implemented in a separated PR

Hi @M123-dev & @monsieurtanuki, I have implemented a big part of the improvements for the scanner/camera.
Everything is not yet finished, but I would appreciate if you could send me your feedback on the current implementation.

Thanks ;)

[g123k]

After discussing with @teolemon, we will measure if these improvements are enough.
And if necessary the start/resume detection will be implemented.

[monsieurtanuki]

Hi @g123k!
As I said before, I don't believe in Isolate. A lot of trouble, and probably not worth it.
We're not talking about heavy processing that makes the app stutter, we're talking about heavy processing that drains the battery. cf. https://www.youtube.com/watch?v=5AxWC49ZMzs
Besides, tomorrow I travel all day long. It's fair to say that you need someone else to approve (or not) this PR.

[g123k]

@M123-dev Do you have a few minutes to review this PR?

[M123-dev]

Heyy @g123k I just had a look at your code, I didn't studied it and I didn't double checked everything but what I read looks good to me.

But I agree with @monsieurtanuki it doesn't solve battery problems (might even add, as we move data to a different threat) but that's not a reason for me to not merge. It assures smoothness in the smoothie main threat thats great.

Also good that you added haptic feedback, just searched for a issue with that to link to this PR but didn't found one. Wonder why I haven't opened one. I've thought about haptic feedback multiple times already.

[M123-dev]

I think adding a private empty constructor is better then doing it like that

[g123k]

An isolate requires a top-level or static function, that's why :/

[M123-dev]

Some merge conflicts @g123k

[g123k]

It should now be OK :)

[M123-dev]

@g123k the analyzer goes wild, I guess a file has change or something like that
