pldm_visualise_pdrs.py: make use of --all

pldmtool platform getpdr has a new --all option that dumps all the PDRS.
Probe pldmtool to see if it supports the --all option and if it does,
use it, as it is at least an order of magnitude faster than invoking
pldmtool once for each PDR.

The pldmtool error handling code is complicated significantly, because
with the much larger json documents being printed by --all, it becomes
important that the json decoder be able to start decoding the document
before pldmtool has sent all the pdrs.

get_pdrs is restructured as a generator selection method, given that
different versions of pldmtool have different capabilities.
