Dependancy issue when install bonescript Debian package

[psiphi75]

When installing bonescript (using apt install bonescript) on a BeagleBone Blue using a Debian command line image I get the following problem.

Setting up bonescript (0.7.3-git20190822.0-0rcnee2~buster+20190903) ...

Installing xz-utils fixes this issue. It would be good to add xz-utils as a dependency to the Debian bonescript package.
