pySim.esim.saip.File: Support pinStatusTemplateDO + lcsi

The tuples defining a DF or ADF in an eSIM template must contain a
pinStatusTemplateDO.  When parsing tuples into a File() instance, we
must save it, and re-create it at the time we re-encode that file.

Same applies to the lcsi (life cycle state indicator), which may
optionally exist for any file.

Closes: OS#6955
