saip.validation: Verify unused mandatory services in header

This adds a new check method to the pySim.esim.saip.validation.CheckBasicStructure
class, which ensures that no unused authentication algorithm related mandatory
services are indicated in the ProfileHeader.

So if a profile e.g. states in the header it requires
usim-test-algorithm, but then the actual akaParameter instances do not
actually use that algorithm, it would raise an exception.

Fix esim.saip.ProfileElementSequence.remove_naas_of_type

This method did not work at all at the moment, likely due to API churn
over time.  This change makes the following exception go away:

Traceback (most recent call last):

A subsequent patch should introduce unit tests to avoid such breakage in
the future.
