read_excel kwarg for `comment`?

[smsaladi]

This is a feature request to add a comment kwarg to pandas.read_excel just like pandas.read_csv can accept a comment kwarg.

Sorry if this request should be placed somewhere else.

It turns out this works already, the comment kwarg gets passed down the generic parsing code, but isn't documented (or likely tested). A PR to flesh this out would be welcome

In [31]: df = pd.DataFrame({'a': ['1', '#2'], 'b': ['2', '3']})

In [32]: df.to_excel('tmp.xlsx', index=False)

In [33]: pd.read_excel('tmp.xlsx')
Out[33]: 
    a  b
0   1  2
1  #2  3

In [34]: pd.read_excel('tmp.xlsx', comment='#')
Out[34]: 
   a  b
0  1  2

I'd like to work on this!

Hi @vertan, @chris-b1, I just submitted a PR referencing this, but I've only done the example for the docs. Perhaps there is more work to do here in terms of tests?
