withFDHandler now explicitly flushes the file handle whenever log entries
are rendered out. Thanks to @filterfish for identifying this omission that
could lead to log messages being dropped.
Upgrade steps: no changes other than updating logging-effect.

1.1.1
withBatchedHandler no longer prints empty log messages. Previously,
if you ran a program that didn’t log but used withBatchedHandler (or anything
that used that), an empty log message would be output. Thanks to @codedmart
for fixing this.
1.1.0
Breaking changes:
MonadLog no longer has logMessage as a function. It now has
logMessageFree which takes a free monoid of log messages. If you were just
using logging-effect then this won’t affect you, as logMessage still exists
with the same signature outside the type class.
MonadLog now comes with a law that states that logging is a monoid
homomorphism. This essentially means that you have to treat all log messages
uniformly.
Pass-through instances for all “stock” monad transformers have been added
(all of transformers, CatchT from exceptions and FreeT/FT from free).
WithSeverity now has instances of Traversable and Foldable
WithTimestamp now has instances of Eq, Ord, Read and Show.
Additions:
A set of convenience functions have been added for quickly logging with
severity. The combinators are: logDebug, logInfo, logNotice,
logWarning, logError, logCritical, logAlert and logEmergency.
mapLogMessage got a companion function mapLogMessageM that works with
monadic tranformations.
