Unable to invoke terraform when line feed is CRLF

[DaemonDude23]

This is mostly for posterity as I've identified the cause of the problem and it's an easy fix.

tfenv 2.2.0

Issue:
If the .terraform-version file is set to CRLF (not LF), and you have an empty newline in it like so:

0.14.6

If you try to run a terraform command or tfenv use 0.14.6, you'll get:

Switching default version to v0.14.6
Default version file overridden by /BLA/BLA/.terraform-version, changing the default version has no effect
No versions matching '' found in remote
/terraform: No such file or directorynv/2.2.0/libexec/tfenv-exec: line 105: /home/linuxbrew/.linuxbrew/Cellar/tfenv/2.2.0/versions/0.14.6
'terraform version' failed. Something is seriously wrong

The fix:
Remove the blank newline, or switch the file's line feed to LF

This really feels like tfenv should be more robust around this. I keep hitting the issue.
