pip-sync should respect pip-compile's output_file configuration

[aentwist]

Expected result

pyproject.toml

[tool.pip-tools]
src_files = ["requirements.in", "dev-requirements.in"]
output_file = "requirements-lock.txt"

pip-sync syncs from requirements-lock.txt

Actual result

looks for requirements.txt

Steps to replicate

1. use undocumented configuration src_files, and configuration output_file
2. pip-compile
3. pip-sync

Proposed Solution

respect the output file

Alternative Considerations

add a pip-sync option
