Add ability to pull information from Pandas DataFrame or AstroPy Table

[jeremykubica]

Building off the pzflow sampling request (PR #181), add the ability to pre-sample data into an AstroPy table or Pandas DataFrame and then retrieve it during sampling.

This could look like:

from pzflow import Flow

my_flow = Flow(file="something.pkl")
sample_table = flow.sample(1000)

flow_results_node = TableSampler(sample_table)
