Deserialization fails for nested structures

[esensar]

Version

• 0.4.1 (and every one before)

Describe the bug
Deserialization of nested structures fails - see #55 (comment) for example
This may also happen in other cases as well, since the issue is caused by trying to read a field name when end of structure is reached, thus moving the current position in input stream and breaking further deserialization

Expected behavior
Deserialization should behave the same, regardless of level of nesting
