[BAM] Add function to slice BAM about fuc

[sbslee]

@harish0201, thanks for the idea! I had to do that multiple times to create "mini" BAMs. I will definitely add the command in v0.8.0 (will call it something like bam_slice).

@harish0201,

I just added a new command called bam_slice to the v0.8.0 version of fuc (0a7588e):

(fuc) sbslee@Seung-beens-MacBook-Air docs % fuc -v
fuc 0.8.0
(fuc) sbslee@Seung-beens-MacBook-Air docs % fuc bam_slice -h
usage: fuc bam_slice [-h] [--no_index] input_bam region output_bam

This command will slice a BAM file. By default, the command will create a accompanying index file (.bai) for the output BAM file.

positional arguments:
  input_bam   input BAM file
  region      target region
  output_bam  output BAM file

optional arguments:
  -h, --help  show this help message and exit
  --no_index  use to this flag to skip indexing

To install the latest v0.8.0 version, clone the repository and install fuc in the following way:

$ git clone https://github.com/sbslee/fuc
$ cd fuc
$ git checkout 0.8.0-dev
$ pip install .

Let me know what you think! If you have additional feature requests, feel free to share as well (in a separate issue).
