dep: update packaged sqlite to 3.43.1

[flavorjones]

From the changelog at See https://sqlite.org/releaselog/3_43_1.html :

• Fix a regression in the way that the sum(), avg(), and total() aggregate functions handle infinities.
• Fix a bug in the json_array_length() function that occurs when the argument comes directly from json_remove().
• Fix the omit-unused-subquery-columns optimization (introduced in in version 3.42.0) so that it works correctly if the subquery is a compound where one arm is DISTINCT and the other is not.
• Other minor fixes.

Closes #396
