Diesel copy nonasync

[jr1221]

Changes

• Switch to diesel no async with a deadpool closure system
• add a data_temp table for the use of temporary tables with an ORM
• add a copy_many that copies into db, then inserts into data. Cannot directly insert into data as there is no conflict handling for COPY statements in postgres.
• Remove the batching logic associated with add_many
