Update CANU From CSM Release Tarball

If doing a CSM install or upgrade, the release tarball contains a CANU RPM. It can be extracted and installed using the following steps.

Procedure

Display the current CANU version.
```
canu --version
```
Set the TARBALL variable to the path and filename of the CSM release tarball:
```
TARBALL=/your/path/here/csm-version.tar.gz
```

Extract the CANU RPM from the tarball:

tar -xzvf "$TARBALL" --wildcards "*/canu*.rpm"

Output should look similar to the following:

csm-1.2.0-beta.81/rpm/cray/csm/sle-15sp2/x86_64/canu-1.2.1-1.x86_64.rpm

Note the path to the RPM from the output of the previous command, and install it:
```
rpm -Uvh <path-to-canu-rpm>
```
Display the new CANU version.
```
canu --version
```
