Allow arbitrary lumped port directions

[nikosavola]

Is your feature request related to a problem? Please describe.
awslabs/palace#75 is now merged and arbitrary rotation ports are supported. The implementation for Palace scattering in gplugins however supports only an orientation from ["+X", "+Y", "-X", "-Y"].

Describe the solution you'd like
Generalise inferring the lumped port direction and use new Palace format for arbitrary orientation

gplugins/gplugins/palace/get_scattering.py
