Fix for crash when compiling module with no parameters.

[gjcoram]

See #103

This is the correct commit. Apparently, having a dummy parameter interns the empty string (possibly the unit or description of the parameter), so that the later lookup of the empty string finds a match.

It seems that this patch follows in a crash compiling psphv version 1.0.6 (see https://github.com/dwarning/VA-Models/tree/main/code/psphv/vacode). Log file attached:

Update README.md to point to this repository instead of pascalkuthe

I guess you went and officially forked this? are you mantaining it?
