O2 Production Release 20

This is the twentieth production release of PyCBC for use in LIGO's second observing run and the first Advanced Virgo observing run.

This release has been tested against LALSuite with the hash:

539c8700af92eb6dd00e0e91b9dbaf5bae51f004

This releases fixes a bug in PyCBC 1.7.10 that causes the cumulative IFAR plots made by pycbc_page_ifar to be incorrect if the code is passed --hierarchical-removal-level 0. This plot is only used for debugging purposes and is not one of the main result plots. The code in pycbc_page_foreground was patched to that it is backwards-compatible with runs that do not do hierarchical removal. The code in pycbc_condition_strain has been modified to allow the dynamic range scaling to be turned off when the code is run on single-precision data.

There are no other changes since the 1.7.10 release.

Details of the changes since the last production release are at v1.7.10...v1.7.11
