b9e76d1bcd Rename parse_lattice_param to parse_lattice_param_from_cell 
Add new definition for parse_lattice_param

Now parse_lattice_param is design to parse Property rather than search for it in cell.
This functionalty was move to parse_lattice_param_from_cell.

86699b42f6 Switch to potentially-sparse net users array 
This uses a new data structure for net.users that allows gaps, so
removing a port from a net is no longer an O(n) operation on the number
of users the net has.

5c30093360 nexus: reduce OSCA worst case to 7% 
The current version of Crosslink-NX Family Data Sheet lists the high
frequency oscillator maximum frequency as 481.5MHz (that is, 7% higher
than its nominal 450MHz):

https://www.latticesemi.com/-/media/LatticeSemi/Documents/DataSheets/CrossLink/FPGA-DS-02049-1-2-1-CrossLink-NX-Family.ashx?document_id=52780

Older documents listed a wider frequency range but ±7% is the range for
production parts.

ddb084e9a8 archapi: Use arbitrary rather than actual placement in predictDelay 
This makes predictDelay be based on an arbitrary belpin pair rather
than a arc of a net based on cell placement. This way 'what-if'
decisions can be evaluated without actually changing placement;
potentially useful for parallel placement.

A new helper predictArcDelay behaves like the old predictDelay to
minimise the impact on existing passes; only arches need be updated.
