SIMULATE f(x) FROM p LIMIT n

[riastradh-probcomp]

• Add SimulateExp AST node like SimulateModelsExp.
• Adapt parse.py to allow it and produce SimulateExp.
• Implement expand_simulate like expand_simulate_models in macro.py.
• Use expand_simulate like expand_simulate_models in compiler.py.

For those looking for this feature, a simple workaround is to create a table of simulations, and use sql select to apply f to the samples.
