Define the file size early if possible.
Some templates (e.g. for 5GS) define files which aren't completely defined.
Fixes the parsing for 5GS SUCI_Calc_Info which doesn't have a file size defined.

In case the fileDescriptor of EF.IMSI is purely template based and only
the file content is given in the actual profile, we must pass a template
reference to the File() constructor before we can read the IMSI.
This fixes the following exception for some profiles:
ValueError: File(ef-imsi): No fileDescriptor found in tuple, and none set by template before

So far we mainly created File() instances when parsing existing
profiles. However, sometimes we want to programmatically create Files
and we should offer a convenience helper to do so, rather than asking
API users to worry about low-level details.

The point of the SAIP template mechanism is to reduce the size of the
encoded profile. Therefore, our encoder in the to_fileDescriptor()
method should suppress generating attributes if their value is identical
to that of the template (if any).

The encoding of the access rule reference is different in FileTemplate

If the API user modifies the size of the body, we need to check if we
need to re-compute the file_size attribute which is later encoded into
the fileDescriptor. The size obviously must be large enough to fit the
body. Let's do this implicitly by introducing a setter for File.body

ProfileElements.insert_after_pe() is a convenience method to insert
a new PE after an existing one in the sequence. This is a frequent

When generating the file content (body), we need to proceed in the
following order:
1a) If FCP contains fillPattern/repeatPattern, compute file content from those
1b) If FCP doesn't contain fillPattern/repeatPattern but template
exists, compute file content from template
2) Apply any fillFileConten / fillFileOffset from the SAIP File on top
of the above

If we know the efFileSize and record_len, but Fcp doesn't contain
the number of records, we can simply compute it.

With this change, the ProfileElementSequence object will maintain a
representation of the filesystem hierarchy of the eSIM profile. Every
file that is added by a ProfileElement will add a FsNode into that tree,
and each FsNode will point to the File object for the respective file.
This allows us to find files by their path, as well as add files by
path.

it and re-constructed the key from File.pe_name - but that's not
