Implement a tool to import VMA files into a Proxmox Backup Server

Example usage:

zstd -d --stdout vzdump.vma.zst | vma-to-pbs \
    --repository <auth_id at host:port:datastore> \
    --vmid 123 \
    --password_file pbs_password

Commit 07/10 requires
https://lists.proxmox.com/pipermail/pve-devel/2024-March/062182.html
to be applied first.

Changes since v4:
* Bump proxmox-backup-qemu
* Remove unnecessary "extern crate" declarations
* Refactor error handling with anyhow
* vma.rs: Improve code readability by adding constants and using more
  descriptive variable/type names.
* vma.rs: Move duplicate code into read_string function
* Print elapsed time in minutes, seconds and ms
* Refactor block device id and size retrieval logic
* vma: Document break statement when reaching end of file
* Use selected imports instead of glob imports
* Split up vma2pbs logic into seperate functions
* Makefile: remove reference to unused submodule

Changes since v3:
* Add the ability to provide credentials via files
* Add support for streaming the VMA file via stdin
* Add a fallback for the --fingerprint argument

Changes since v2:
* Use the deb packages from the proxmox-io and proxmox-sys dependencies
  instead of the proxmox submodule
* Remove the proxmox submodule
* Update the proxmox-backup-qemu submodule to make it buildable with
  the newest librust dependencies

Changes since v1:
* Remove unused crates and uses
* Format the code
* Use anyhow for error handling
* Use clap for parsing arguments instead of getopts
* Fix blocks being reindexed on every read
* Make sure ProxmoxBackupHandle is dropped properly on error
* Move image_chunk_buffer from stack to heap
* Move the block_index in VmaReader to the heap completely
* Initialize vectors with `Vec::with_capacity` and `resize` instead of
  the `vec!` macro, to potentially improve performance on debug builds.
* Add comments to code filling the MD5 sum field with zeros
* Change device_id arguments to usize
* Handle devices that have a size that is not aligned to 4096 properly
  in read_device_contents, when the caller provides a buffer that would
  exceed the device size.
* Avoid unnecessary loop iterations in read_device_contents when the
  buffer size is not aligned to 65536
