DEV: Refactor uppy s3 mulipart mixin to not use self = this (PR #14960)

We no longer use this pattern, so we can replace with function binding instead.


Using @bind decorator on methods is preferred instead

Huh TIL, nice!

is this initialised to null somewhere ?

btw. I think that could be a constant

yes I don’t see this being altered later on ?

@jjaffeux @CvX fixed that retryDelays thing, is there more that needs to be done here or can I get an approval to merge?

const RETRY_DELAYS = [0, 1000, 3000, 5000];
