flexible line terminators

Is your feature request related to a problem? Please describe

Hi,

Could asdf open up the line terminator sequences supported in .tool-version files?

• LF (modern)
• CRLF (Windows)
• degenerate mixtures of LF/CRLF in poorly formatted text files

In asdf 0.15 and earlier, we seem to get subtle problems with .tool-version files that contain CRLF.

Perhaps a newer version has already addresed this. But I though I'd ask on behalf of users stuck on some older release versions.

Describe the proposed solution

Use a generic buffered line reader to perform line termination delimiting in an OS agnostic way.

To mockup an AST regex, /\r*\n+/m

Describe similar asdf features and why they are not sufficient

Not applicable.

Describe other workarounds you've considered

asdf is peerless!
