Alter default configuration

Explain how the module logging destinations work, remove the specified
logging destination, because the global log definition already logs to
stderr.

libimagstore logs with trace now, also to a logfile in /tmp/

imagrc.toml

+# Note that the `destinations` key is for _additional_ destinations to the
+# default destination in `imag.logging.destinations`, not as replacement! So
+# specifying stderr (`-`) in `imag.logging.destinations` _and_ in, for example,
+# `imag.logging.modules.libimagstore` yields each log line twice, which might
