feat: allow struct slice and struct array for valueType

[cia-rana]

Description

Allow struct slices and struct arrays for valueType (including Header and enc.EncodeHeader). However, this does not apply to two-dimensional arrays, etc.

Fixes #69

that's not what we agreed to. We agreed that enc.EncodeHeader would understand a slice argument so you could encode it youself.

Your change breaks the backward compatibility which is unacceptable

[cia-rana]

Does func valueType inside enc.EncodeHeader cause an error for non-structs?

[cia-rana]

Do you agree with reimplementing enc.EncodeHeader to recognize slice?

[jszwec]

Yea, that's what we discussed in the issue

I updated at 6a7ba1b.
Let me know if need to add test cases or update the documentation.
