nbdfuse, part of the libnbd project, can do this (with writes).  In
fact there is an example of doing exactly this in the manual:

https://libguestfs.org/nbdfuse.1.html#Use-qemu-nbd-to-read-and-modify-a-qcow2-file
https://gitlab.com/nbdkit/libnbd

By the way I would be extremely wary of any tool which claims to
process qcow2 files but is not using qemu code to do it.  nbdfuse uses
qemu-nbd (ie qemu code).
