forkdb for Python

The forkdb SQLite extension, prebuilt, plus a few lines of Python to load it. Unstable first release (0.1.0): everything may change (see docs/STABILITY.md in the repository).

pip install forkdb

import forkdb
host = forkdb.connect()                       # sqlite3.connect(':memory:', uri=True) with the extension loaded
host.execute('select forkdb_init(?)', ('/tmp/s.fk',))
main = forkdb.open_branch(host, '/tmp/s.fk')   # the branch 'main'
host.execute("select forkdb_fork(?, 'main', 'a')", ('/tmp/s.fk',))
a = forkdb.open_branch(host, '/tmp/s.fk', 'a')

Wheels exist for Linux x86_64 (manylinux_2_28), macOS arm64 and Windows x86_64, and carry no dependency on the Python version. The macOS wheel has been tested only in CI, on GitHub's macOS runner, not on a Mac by hand. Elsewhere, build the extension from the repository and point FORKDB_EXTENSION_PATH at it. Your Python's sqlite3 must support loading extensions (Connection.enable_load_extension); forkdb.load says so if it does not. The SQLite behind it must be 3.24 or later.
