Add sqlite_stat1(-4) tables to hidden table list

[simonw]

Running ANALYZE creates a new visible table called sqlite_stat1: https://www.sqlite.org/fileformat.html#the_sqlite_stat1_table

This should be added to the default list of hidden tables in Datasette.

[simonw]

Depending on the SQLite version (and compile options) that ran ANALYZE these can be called:

• sqlite_stat1
• sqlite_stat2
• sqlite_stat3
• sqlite_stat4
