Adopt hdf5-rust

Hi all.

The [hdf5-rust](https://github.com/aldanor/hdf5-rust) project is currently not actively maintained by the author, with the consequence of no new releases on crates.io and a number of issues related to the maintenance of the project.

As part of the discussion the owner has been willing to move the project to some suitable organisation https://github.com/aldanor/hdf5-rust/discussions/299#discussioncomment-10531381. I want to know if the georust community is accepting of this sort of crate and whether I can propose author of `hdf5-rust` transfer the project to the `georust` organisation.

As for me: I have been actively maintaining the hdf5 crates, and have created a [fork](https://github.com/metno/hdf5-rust) to benefit downstream users. I am also a maintainer of [georust/netcdf](https://github.com/georust/netcdf), which targets mostly the same audience.
