Difficulties with cpm tools config to support all pc cp/m-86 formats

sort out why cpmtools refuses to work with 320kb (for testing I use single face 160K  images). ibmpc-514ds does not seem to work. 
depending on libdsk usage, format support changes too
- 320k
- 160k
- 720/1440k
and
- CP/M-86 vs CP/M-86+
