fix: Remote source last slice behavior

[fbuccioni]

I fix a problem on some development web servers that doesn't send the last chunk when in the end bytes range of the request, the value exceeds the size of the file, this problem throws an AggregateError: Request failed, also reported in #218.

To solve it I just implement a small change on src/source/remote.js file.

Thanks for the fantastic library, have a great day.

Solved linter issues.

Any news on this, this change will be a relief for many developers. If you want to request a change in code, code styling or any change please tell me and I will do,

Thank you for your contribution!

Does #474 end up solving the same problem? I could imagine a use case that bypasses the BlockedSource, so if you have examples where that change doesn't remove the AggregateError: Request failed but this PR does, that'd be great to add as a test case! Otherwise I'm probably leaning towards fixing it in the BlockedSource. Upon further reflection, don't believe these are related.

I noticed this other comment that claims that we always have an off-by-one issue here—I'm still investigating, but would you agree based on your own observation or testing?
