V0.4.3

Very minor release, just so that downstream code can take advantage of several fixes and new features.
Also, this release restores the WASM/WASI build which broke due to from_chars compatibility across toolchains.

New features

• Natural ordering for strings is now supported in order-by by all commands (as the new default)
• order-by directives can be typed, like asc:float or asc:f will parse entries as float and sort them accordingly.

Breaking

• s:enable.* has been reworked as an overload of s:when. Use it as s:when.*.
• Default string comparisons are now following natural ordering, which might break things.
