Logging scheme must be updated..

[Ky5595]

Right now, crispor logs have bwa output logs in them making the logs look very confusing.
Also for multiple sequences in one fasta file, It's hard to track which sequence is being processed at the moment and what is the particular guide being used for offtargets extraction.

Solution -
Something like CCTop logging scheme can be done. python print buffer must be taken into account in order to take care of bwa output statements.
Bonus -
If we can show live percentage of the task completed on the command line,that would be great.
