Add support for FixedPointParameters with negative number of integral bits. #406
Description
This is required to support fixed point formats with value ranges like [-0.5, 0.5), e.g.
Q-1.16 on 16 bits:
0x8000 -> -0.5 (32768/2^17)
0x7FFF -> 0.499984
Q-2.17 on 16 bits:
0x8000 -> -0.25 (32768/2^17)
0x7FFF -> 0.249992
For those formats number of integer bits needs to be set to negative value.

Can you clarify why you have put these numbers of 16 bits container and not 32 bits?
Q format is defined as per https://en.wikipedia.org/wiki/Q_%28number_format%29
So Q1.16 number should be define on 32 bits container.
