[FEATURE] Create 10K OMOP CDM Patient Sample

[TheCedarPrince]

We need to create a 5K OMOP CDM patient sample for HealthSampleData. This is a rather complex process but can be accomplished in the following steps:

• Set-up a PostgreSQL DBMS on a server
• Generate Synthetic OMOP CDM Data using Synthea
  • Install Java on a server
  • Install Synthea v3.0.0
  • Enable export to CSV (see this: https://github.com/synthetichealth/synthea/wiki/CSV-File-Data-Dictionary)
  • Run synthea jar like `java -jar synthea -s 12345 -p 10000
  • Extract output/csv to directory for loading process
• Load synthetic OMOP CDM data into DBMS
  • Install R on a server
  • Install this package: https://github.com/NACHC-CAD/ETL-Synthea
  • Download Athena vocabularies (see: https://athena.ohdsi.org/search-terms/start for downloading)
  • Create zipped vocabularies into a directory called vocab in the same directory as output/csv
  • Execute tutorial in https://github.com/NACHC-CAD/ETL-Synthea
• Export PostgreSQL database into SQLite
• Share SQLite export with @TheCedarPrince for hosting

That is the overall process but rather complex. Happy to support each step along the way.
