Compress no longer available

[jasonhoule]

Describe the bug
The compress command is no longer available on Debian based systems. It still appears to be available in Unix and BSD systems. In LzwStreamWrapp::checkBinary() there is a check for both compress and uncompress. When attempting to extract a .tar.Z file the extract fails because of the isBinaryAvailable() check but uncompress is in fact still available.

The archive xmlfeed_lic475-2021_09_24.tar.Z could not be extracted. compress and uncompress commands are required

Configration (please complete the following information):

• OS: Ubuntu 20.04.3
• Version of library: 1.4.14

To Reproduce
Attempt to extract a LZW compressed .tar.Z file on newer debian systems where compress is not available or installable.

Expected behavior
Perhaps there could be a separate check. If writing to the archive then check for compress? Please take a look at the below. If that works for you then I can submit a pull request
