Optimization of sched_ue methods to derive required number of prbs to allocate to a rnti
...
This optimization has been achieved by:
- implementation of "false position method" root-finding algorithm
- application of the false position method in cc_sched_ue::get_required_prb_dl/ul(...)
The number of iterations in the worst case scenario, reduced from 100 to 5 with
the proposed algorithm.

fix derivation of UL-64QAM support from the UE Capabilities in the eNB
...
Before this PR, the eNB was not activating UL-64QAM if the UE release was below 12,
due to an erroneous convertion of the ASN1 EUTRA Capabilities struct into the flattened
srslte::ue_capabilities_t.
With this PR, the eNB activates UL-64QAM for the following cases:
- UE category 5
- UE category 8 and release >= 10
- UE category UL 8 and release >= 12
