Added script to generate mimic-iv concepts for PostgreSQL.

Hi @alistairewj

I moved the original PR now to mimic-code. Sorry that it took so long.

I've created a routine to build concepts for PostgreSQL based on the existing mimic-iii code. It seems that the mimic-iv concepts changed in version 1.0 because further changes were necessary compared to v0.4. Honestly, I think the concepts/postgres_make_concepts.sh is a little messy, but nevertheless I thought it might be useful for others, and it can serve as a starting point for future development.

• postgres-functions.sql: identical to mimic-iii mimic-code/concepts/postgres-functions.sql except the schema was set to 'public'
• postgres_make_concepts.sh: used loop structure from concepts/make_concepts.sh and added some regexps. Also, it runs twice for the subfolders score and sepsis to handle interdependencies between folders.
• Readme.md: updated paths for mimic-code and documented the usage (copied from mimic-iii) and known problems

Following the instruction in Readme.md generates all concept except suspicion_of_infection and sepsis3. I attached the output of the script.

Please let me know if there is anything to improve.

Cheers!

Thanks! Got two PRs for this so merging them on an internal branch.
