Temperature usermod: update OneWire to 2.3.8

[iammattcoleman]

OneWire 2.3.8 includes stickbreaker's and garyd9's ESP32 fixes, making blazoncek's fork no longer necessary.

This updates the dependency and removes the comment suggesting blazoncek's fork.

I noticed some minor issues that were unrelated to the OneWire version change, so I put them in separate commits prior to the final commit that's the focus of this pull request:

• One of the files had CRLF endings, which my IDE warned me about when I tried to commit my changes to it.
  I ran git ls-files --eol | awk '$1 == "i/crlf"' and found three other files in the codebase with CRLF endings.
  So, I figured I should go ahead and make the whole codebase uniformly use LF endings.
• The Temperature usermod's changelog sections weren't rendering properly, so I added blank lines to fix it.

It will probably be the fastest/easiest to review if you view the diffs for each commit separately.

I do appreciate the effort but changing CRLF formatting is for the maintainers or original authors to perform.
I am the author of boblight and maintainer of dallas temperature usermods.
As for OneWire and Dallas usermod, the platformio.ini was already updated to use library version 2.3.8 so the only acceptable change is modification of readme.md

Thank you for the feedback @blazoncek.

In all cases, the CRLF-terminated files were alone in a directory of otherwise LF-terminated files. So, they all look to be unintentional but I certainly don't want to offend anyone. I'll drop the line-ending commit.

Would you like me to retain the commit that fixes the Temperature usermod's changelog Markdown rendering?

Also, shouldn't the Temperature usermod's platformio_override.ini be updated in addition to the readme? If I leave it as it currently is, people using the Temperature usermod might accidentally use the older version or might unnecessarily use your fork.

[blazoncek]

MD changes are fine with me.
PlatformIO overrides are also ok but in reality I don't think people use them as most have been copied to global sample file.

CRLF madness is a consequence of working on Win & mac systems without using a GH (changes made that not yet belong to a commit).

[iammattcoleman]

@blazoncek I've removed the line-termination change.

[iammattcoleman]

@blazoncek I rebased my feature branch on top of the current state of the 0_15 branch.
