Read all parameters listed in params. This calls only classmethods, so each entry in params can either be a class or some ConfigurableParameter implementations return more than one key-value pair, for example, Imsi returns
an instance of a class, of a (non-abstract) ConfigurableParameter subclass. For example, params = [Imsi, ] is both 'IMSI' and 'IMSI-ACC' parameters.

For additional_sd_keys=True, audit also all Security Domain KVN that there are *no* ConfigurableParameter e.g.

Read all parameters listed in params. params is a list of either ConfigurableParameter classes or
ConfigurableParameter class instances. This calls only classmethods, so each entry in params can either be the
class itself, or a class-instance of, a (non-abstract) ConfigurableParameter subclass.
For example, params = [Imsi, ] is equivalent to params = [Imsi(), ].
For additional_sd_keys=True, output also all Security Domain KVN that there are *no* ConfigurableParameter
subclasses for. For example, SCP80 has reserved kvn 0x01..0x0f, but we offer only Scp80Kvn01, Scp80Kvn02, subclasses for. For example, SCP80 has reserved kvn 0x01..0x0f, but we offer only Scp80Kvn01, Scp80Kvn02,
Scp80Kvn03. So we would not show kvn 0x03..0x0f in an audit. additional_sd_keys=True includes audits of all SD Scp80Kvn03. So we would not show kvn 0x04..0x0f in an audit. additional_sd_keys=True includes audits of all SD
key KVN there may be in the UPP. This helps to spot SD keys that may already be present in a UPP template, with key KVN there may be in the UPP. This helps to spot SD keys that may already be present in a UPP template, with

For der_size=True, also include a {'der_size':12345} entry.
