Fix: numeric energy input for ARKANE

[jeehyunatrmg]

Motivation or Problem

I wanted to manually put energy in Arkane input file since Arkane doesn't contain model chemistry that I used. However, Arkane assumed float type as 'path' and giving out the error.

Description of Changes

added lines that can recognize the float type before it assumes as the path

Testing

it worked in my laptop..?

Reviewer Tips

Actually, Jerry did this fix...

I would suggest putting the check in the same statement: if hasattr(energy, 'path') and not os.path.isfile(energy.path)

Also, I'm not sure if Alon has opinions on use of hasattr vs checking isinstance(energy, Log).

I think isinstance(energy, Log) is cleaner, and it should definitely be in the same statement.
@jeehyunatrmg, we can do it together tomorrow if you'd like, or simply go-ahead and make these fixes.

We can either use this PR or @goldmanm's commit. This PR could also be a good practice. Either way we should also add a test.
