`find_spans()` of `CheckableChunk` only checks for linefeed as newline.

[KuabeM]

Describe the bug

Method find_spans() in chunk.rs only recgonizes a linefeed as newlines, but should also acknowledge CRLF and friends. See FIXME in chunk.rs:219.

To Reproduce

Steps to reproduce the behaviour:

1. A file containing \r\n as newline
2. Run cargo spellcheck on that file
3. find_spans() will be broken

Expected behavior

Everything works on files with \r\n as expected.

Please complete the following information:**

• System: Arch Linux
• Obtained: git
• Version: cargo-spellcheck 0.4.7-alpha.0

I'm investigating this in branch korbinian-fix-find-spans, I've just pushed a first guess (which isn't working :disappointed:) plus a unit test. I'll open a PR if I found a proper solution.

Hopsa, I guess I should have a look again :D thanks for the reminder!

[drahnr]

No worries, also #137 ;) - might be easier to do it at all at once

[drahnr]

Any roadblocks I could help with?

[KuabeM]

Nope, just me not having enough time. As you suggested I'm actually doing #137. It makes more sense to rewrite the whole thing
