SequenceOf/SetOf to remain a schema objects (#162)
* Add `omitEmptyOptionals` encoder option
Added `omitEmptyOptionals` option which is respected by `Sequence`
and `Set` encoders. When `omitEmptyOptionals` is set to `True`, empty
initialized optional components are not encoded. Default is `False`.
* Change `SequenceOf`/`SetOf` behaviour
- New elements to `SequenceOf`/`SetOf` objects can now be added at any
position - the requirement for the new elements to reside at the end
of the existing ones (i.e. s[len(s)] = 123) is removed.
- Removed default initializer from `SequenceOf`/`SetOf` types to ensure
consistent behaviour with the rest of ASN.1 types. Before this change,
`SequenceOf`/`SetOf` instances immediately become value objects
behaving like an empty list. With this change, `SequenceOf`/`SetOf`
objects remain schema objects unless a component is added or
`.clear()` is called.
- Added `.reset()` method to all constructed types to turn value object
into a schema object.
