[FEATURE] Use get_pse_data with a list of symbols with parallelization

[ajdajd]

Is your feature request related to a problem? Please describe. While I can use a for loop, fetching recent PSE data is slow. It takes around ~30s to get the last ~30 days of JFC. See below.

Describe the solution you'd like Use joblib.Parallel (PR incoming)
