Improving VPR I/O

" summary

Work on verilog-to-routing's P&R tool VPR makes the arch and routing file I/O faster file parsing and closes correctness gaps in how architecture and routing resources are read and validated. Changes include a stricter parser with added validation tests, fixes for corner-case routing formats, and integration into SymbiFlow's Artix 7 flow so generated bitstreams use the updated loader. Results show reliable loads and reduced startup latency when running VPR under the Artix 7 toolchain.
