Very experimental support of Quantum LTO HH drives

Description

I would like to add the Quantum LTO HH drives to support list using multi-vendor drive support framework. Actually I don't have any Quantum drives but I believe this change works fine if Quantum LTO HH drives has almost same behavior as IBM LTO HH drive.

Actually I don't know its is almost same or not. So I also would like to ask Quantum drive users to confirm the behavior.

Hello @piste-jp-ibm good afternoon, writing just to thank you for your great work and let you know I followed some of the tips from the wiki, as well as previous issues and other sources, and got ltfs working great on my Ubuntu 21.04 machine using a Quantum LTO-8 HH drive.

Here's the procedures I've followed:

1. Install dependencies:

sudo apt install autoconf automake libtool libicu-dev icu-devtools libfuse-dev --
libxml2-dev uuid-dev libsnmp-dev build-essential tgt

2. Run ./autogen.sh
3. Dealt with icu as per icu-config deprecated #153, changing the configure.ac and replacing icu by icu-ic and creating the icu-config file with the script:

#!/bin/sh

opts=$1

case $opts in
  '--cppflags')
    echo '' ;;
  '--ldflags')
    echo '-licuuc -licudata -ldl' ;;
  *)
    echo '/usr/lib/x86_64-linux-gnu/icu/pkgdata.inc' ;;
esac

4. Then I've run the next steps with no issues, only small warnings:

./configure
./make
sudo make install 

5. Finally, loaded the new libraries with sudo ldconfig -v and everything went fine! ltfs, mkltfs and ltfsck tested and working as they should:
