> So far we assumed that all `RecoverableWriters` support "resuming", i.e. after recovering
from a failure or from a savepoint they could keep writing to the previously "in-progress"
file. This assumption holds for all current writers, but in order to be able to accommodate
also filesystems that may not support this operation, we should check upon initialization
if the writer supports resuming and if yes, we go as before, if not, we recover for commit
and commit the previously in-progress file.
