Update README.md to be more gender inclusive

[p10q]

Nice project and generally nice attitude in the README! And I realize the main author is a woman, and it's easy to make mistakes with these things (I have). But it's good to avoid little micro expressions that encourage only 'fellas'.

@p10q Thank you for creating this pull request. I need a little change in the commit message before I merge this. The current commit message body is a long line (longer than 72 characters) which deviates from the commit message conventions I have been following. This can be seen in the output of git log.

Would you please update the commit message body and restrict the line lengths to a maximum of 72 characters?

Here are the steps you would need to follow:

git checkout patch-1
git commit --amend

# When the editor comes up, edit the commit message body and ensure that
# all lines are wrapped to a maximum of 72 characters. Save and quit the
# editor.

git push -f origin patch-1
