It would be great if we could pass into analyze specific checks that I am interested in, say only find by iso_codes, so Money::Currency.analyze(str, :iso_codes) or similar.

My project has the ability to set have free text input and I was analyzing on my end just using iso_codes from Money::Currency.all.map(&iso_codes), but this gem would be much better than my bad Regex. Problem is, for say d + 1, I don't want to get the currency as it can be user defined variable. So just having ability to check for iso_codes, so I don't need to manually test 12USD + 2. Anyways thought I'd drop these thoughts in here and maybe I'll be able to set up the fork and do this myself.

P.S. I wanted to contribute this change as it seems to be pretty straightforward, but being new to open source contribution couldn't get the tests to run due to it asking to add gem to the gemfile as I perhaps Bundler is using the install money, so I didn't manage to get the fork working
