Utilize Crashlytics logging instead of print statements

We should also update AGAudioPlayer/BASS gapless to support a custom logging callback function to track all of this.

This looks like a good way to centralize logging: https://github.com/emaloney/CleanroomLogger

os_log seems like a disaster for us: no way to collect anything after it is sent

CleanroomLogger #69

For all those reasons and many more that I could expound upon at great length, I will never be adding Cocoapods support to this or any other project I maintain.

This decision is final and will not be revisited. If this rules out CleanroomLogger for you, then I'm sorry this package couldn't meet your needs; I hope you can find one that does.

There are a ton of forks of the project to add a Podspec. I don't see one that appears to be long lived and maintaining a Podspec though. This is the longest lived fork that I could easily find, so I guess we can go with that and make our own fork later if necessary.
