v0.3.13

[eafer]

This release adds support for the upcoming 6.14 upstream kernel, and for
a handful of RHEL 9 kernels that have been broken for a while.

Some improvements have been made to ENOSPC behaviour, but the work here
isn't quite finished yet.

Read-only support is added for fusion drives. Writes will probably never
get implemented, though I might reconsider this if people actually ask
for the feature.

Read-only mounts of volumes with so-called "dataless snapshots" are also
tentatively allowed. I have no idea what this is about but there should
be no risk.

Free space as reported by statfs is now much more accurate. A few other
bugs were also fixed, but nothing big enough to deserve notice.
