Remove sqlalchemy, only psycopg2 is needed for SQL now and comment out original send_data_to_db() (2023-04-20 19:28:59 +0200)

When testing out your program, I ran into some error ("... multiple schema ...") when inserting data into the database.
I was not able to find a fix for this error, so I decided to make a fix for this by sending data to the database using only plain SQL and psycopg2.

• sort imports
• format code
• Add types everywhere
• Just specify datatypes as strings and create tables before insert
• Create own function to send data to db (just the skeleton)
• Create table if not exist and beginning for insert command
• Only import required things
• Some test data for merged GSA and GSV
• Fix some column_casting data types
• Insert dataframes in database using psycopg2 and template SQL statement
• Replace pd.NaN and pd.NaT with None, because they are incompatible with psycopg2
• Remove sqlalchemy, only psycopg2 is needed for SQL now and comment out original send_data_to_db()
