feat: Sendable collections improvements

[PhilippeWeidmann]

I chose to not reimplement the whole RangeReplaceableCollection protocol but rather add methods when needed.

I just have a small proposal regarding how we check assertions.

Note: Something I do not really like today is the fact SendableCollections are classes (For the record I wrote it this way for convenience). I mean it does work but you can write a let and mutate it, breaking with expected swift collections behaviour. Just saying that might be something else we could improve.

Yup totally agree

Thanks for updating the code.
