BigInt support?

[danielberndt]

Passing a BigInt to filesize causes an exception (in Chrome 98, but it's probably the same in all other envs too):

Uncaught TypeError: Cannot convert a BigInt value to a number at isNaN ()

Given that BigInt is widely supported these days it could make sense for this library to also support it as an input.

Curious about your thoughts!
