Replace aiffSampleRateTable unordered_map to ieee80 converter

[alxarsenault]

I found a way to remove that enoying global aiffSampleRateTable unordered_map.
This is highly based on this code https://gist.github.com/Angeldude/e5291417f2eb00d81f7c.

I've wanted to get rid of that table for ages - nice! My only question is that I don't know the licence of the gist you based it on... we should add an acknowledgement to the library at least... but maybe there are other requirements in a licence somewhere?

[alxarsenault]

I don't really have an answer for that. An acknowledgement for sure yes. I feel like the code has been modified enough for it not to be subject to the license.

Seems to have been taken from here.

I actually happen to own that book and I think the code in on the cd that came with it.

Hey, I finally got around to looking at this, sorry it took me so long. I wasn't very keen on using some code already out there (partly for attribution issues but also I found it quite hard to understand and I like to have a grasp of what's going on). So I ended up diving into the topic and have written my own encode and decode functions for the AIFF sample rates now. It's on the develop branch now. Thank you for inspiring me to take a look at this! I'd add your names to the contributors list in the README, but you're already there :)
