deprecate financial package?

[millermedeiros]

it feels weird to have these methods, I used them in the past (that's why I wrote them) but I guess this project isn't really the place for it. All the other methods are more generic or cover common JavaScript problems, actuarial math is a specific domain and should be handled by a separate project.

PS: if deprecated I will create a new repository to keep these methods.

I released v0.10.0 (which contains the financial methods) but deprecated it afterwards. now they are located at the MM_js_lib project (aka. where my code goes to rot).

These methods don't belong here, they should be a separate project - which I probably wont ever release since my day-to-day work don't require this kind of stuff that often... just a FIY in case you need these methods you know where to find it.

PS: I already removed them from the online docs to discourage usage.
