Triqler

* Experimental support for MaxQuant MBR
* Added Dinosaur converter
* Fixed some converter scripts Python 3 compatibility (12)
* Fixed problem with standalone percolator input for dinosaur converter
* Add support for disabling multithreading (by setting --num_threads 1)

* Added issued command to log
* Fixed MaxQuant converter with fractionated data (10)
* Fixed small issues with posterior distribution package

* Added support for converting Quandenser and MaxQuant results to Triqler input format (5)
* Added support for printing posterior distributions to a file
* Added support for plotting posterior distributions and hyperparameter estimation fits

* Fixed problems with CSV reading and writing on Windows (9)
* Fixed lambda function pickling problem with multiprocessing on Windows (8)

* Fixed empty columns as extra proteins issue (4)
* Improved logging messages
* Optimizations for very large datasets. Replaced some operations on python lists by their numpy equivalents to speed up calculation on larger datasets. Also, we now skip the posterior calculation for proteins with identification PEP = 1.0, since they will never be differentially abundant anyway.

* Fixed windows multiprocessing error more elegantly (2)
* Suppressed warnings from child processes (3)
