This is quite an issue: validate_type() should not be used in validate_header() and invoke separately after validate_header(). This way we can just pass EOF1Header to validate_types() and use its .get_type() method.
But maybe this requires a separate PR. What do you think @gumb0?

Sounds good to try in a separate PR.
It made sense to do it here before, becase "validate header" really meant "validate header and types and return them togethere in one struct"

We don't need to store the size at all, because header validation guarantees that type_section_size == code_sizes.siz() * 4
Introduces `EOF1Header::get_type` function to read individual EOF code types. This is fast procedure because we need to read at most 4 bytes and a know offset. By doing so we avoid allocating separated vector to types.
