Utilize # specifier to implement Display trait for SI unit

[EFanZh]

So that it is possible to use {} for decimal units (KB, MB, GB), and {:#} for binary units (KiB, MiB, GiB).

This seems rather ad-hoc to me. I would prefer explicitly naming the unit rather than having this be done ad-hoc with formatting specifiers.

KB by default looks strange to me. Never have I met a programmer thinking in decimal units instead of binary units.

+1 for this.

Seem the repo is not maintained for some time. I forked this repo to https://github.com/foyer-rs/bytesize and made some differences.

Differences from the original bytesize

• Use SI format by default with Display.
• Use "KiB" for SI unit.

Considering the changes, the version of foyer-bytesize crate starts from "2" to differ from the original bytesize crate.

FYI: https://github.com/foyer-rs/bytesize#differences-from-the-original-bytesize

If you need the features, you can use foyer-bytesize as:

bytesize = { package = "foyer-bytesize", version = "2", features = ["serde"]}

And I'm happy to either help to maintain the repo, or contribute back to the upstream if the author is still maintaining this repo.

Hi, folks. I am currently responsible for advancing the development of bytesize with two other developers. In the next release version, bytesize will use IEC units by default.
