dathere/qsv 0.65.0 on GitHub

Major refactoring of main variants - moved redundant code to a new module - clitypes.rs.
Added custom exit codes. Removed --exitcode option in several commands as qsv now returns exit codes for ALL commands in a standard way. #460
Major refactoring of CI test helpers in workdir.rs

py: use python interning to amortize allocs #457
search & searchset: return num of matches to stderr; add --quick option; remove --exitcode option #458
extsort: improved error handling
fetch & fetchpost: better --report option handling #451
lua: faster number to string conversion using itoa and ryu
replace: removed --exitcode option; return number of replaced patterns to stderr
sortcheck: --json options now always cause full scan of CSV
stats: expanded usage text, explicitly listing stats that require loading the entire CSV into memory. Mentioned data type inferences are guaranteed.
cargo update bumped several dependencies
pin Rust nightly to 2022-08-27

py: batched python processing refactor. Instead of using one GILpool for one session, py now processes in batches of 30,000 rows, releasing memory after each batch. This resulted in memory consumption levelling out, instead of increasing to gigabytes of memory with very large files. As an added bonus, this made the py command ~30% faster in testing. 😄 #456
