cir_query fails with whitespace search strings

Bug report by a user:

Hello Eduard
I think your R package webchem is really great and i use it a lot. However, I have one addition to the documentation that you could consider adding.

In the cir_query, you only list chemical names without whitespace and that works fine, but if you have chemicals such as acetic acid, it doesn't work. But by searching for acetic%20acid, the correct chemical is found. It took some time for me to wrap my head around this and maybe there are others that could benefit from this info. It would be pretty easy to add a gsub substituting the whitespace, so it could be something you could consider for our next update.

Best regards
Lasse Nielsen
