Go code generator variable 'model' conflicts if SYSL model has a field named 'model'

[alextmz]

Description

Not sure if my usage is up to date or correct, so let me know if not.
When using the branch anzdaddy/relgom, the Go code generated can be invalid (not compilable) due to a naming conflict if the SYSL model used has a field of name 'model':

!table something:
      model <: something

Can provide more details in private. There is a write-up ready that cannot be posted here.

Steps to Reproduce

1. Have a model with a field named 'model'
2. Generate Go code using branch anzdaddy/relgom
3. Try to compile the code - type mismatch errors are thrown

Expected behavior

Compilation successful

Actual behavior

Compilation fails - type mismatch errors are thrown
