v0.2.7

Added

• librawstor tracks I/O latency breakdown (submission/round-trip/callback/total), retry counts, concurrent in-flight requests, and the 10 slowest requests, reporting them to stderr from rawstor_terminate(). Collected by default; pass --disable-telemetry to configure to opt out (no-op and zero-cost when disabled).
• Publish the Python bindings as a single abi3 wheel (Python >= 3.9), dynamically linked against a separately-installed librawstor, alongside the existing python3-rawstor deb/rpm packages.
• rawstor create/list/info fall back to the RAWSTOR_LOCATION environment variable when LOCATION is omitted from the command line.
• rawstor info rounds used/available/total to a human-readable unit by default (e.g. ~140G instead of 147357440K), prefixing rounded values with ~; -b/-k/-m/-g/-t/-p/-e force a specific unit instead.
