py-apsw: updated to 3.43.1.0

3.43.1.0

All C code calling into Python and all C code called by Python uses vectorcall / \ 
fastcall (see PEP 590) which reduces the overhead of passing and receiving \ 
positional and keyword arguments. (APSW issue 477 APSW issue 446):

Conversion of arguments from Python values to C values drops generic \ 
PyArg_ParseTupleAndKeywords in favour of direct processing which is more \ 
efficient and allows better exception messages.
Running speedtest with a VFS that inherits all methods went from being 17% \ 
slower than pure SQLite to 2% slower.
A virtual table benchmark takes 35% less time. (Remember that benchmarks are \ 
best case!)
The shell JSON output modes have been fixed. Mode 'json' outputs a json array, \ 
while mode 'jsonl' does newline delimited json objects, aka json lines. (APSW \ 
issue 483)
