Hello Max, Neels Hofmeyr, Jenkins Builder, Holger Freyther,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/416

to look at the new patch set (#11).

Add decoding of compressed bitmap in EPDAN

Implemented tree based algorithm to decode compressed bitmap in EPDAN
as described in section 9.1.10 of 3GPP 44.060.
This algorithm intends to improve the performance over existing method.
New Regression test is added under bitcomp directory.
Test case is added to validate decompressed result of the bitmap
Present in EPDAN.
Test is done for multiple bitmaps of varying length.
Invalid inputs are also part of the test vector.
