A very minimal `Log` output implementation for testing of body-image*, barc*
and related crates, and for use with `barc-cli`. Output is directed to
STDERR. When logging with tests, a `TEST_LOG` environment variable is read to
configure a course-grained logging level:

`TEST_LOG=0`
: The default, no logging enabled.

`TEST_LOG=1`
: The `Info` log level.

`TEST_LOG=2`
: The `Debug` log level, but dependencies are filtered to `Info` log level.

`TEST_LOG=3`
: The `Debug` log level (for all).

`TEST_LOG=4` (or higher)
: The `Trace` log level (for all).

## Minimum supported rust version

MSRV := 1.39.0

The crate will fail fast on any lower rustc (via a build.rs version
check) and is also CI tested on this version.
