Store parasitics data from estimate_parasitics into ODB and use write_spef to write them

[eder-matheus]

Description

Instead of using the simple spef writer implemented in resizer to write the spef file from estimate_parasitics, store the parasitics data in odb and write them with write_spef command.

This is necessary since write_spef already covers multiple corner cases regarding the spef format, and mimic them in the resizer implementation would be code duplication.
