fix: decoder on component expansion

[muktihari]

• Now component expansion will expand the expanded component (the destination field) that can itself requiring expansion.

• The expanded component candidate's value now will be matched with the scale offset with the destination field.

• Accumulate and bits calculation is in uint32 since Profile.xlsx (on Bits's comment) says:

  "Current implementation only supports Bits value of max 32."

  • When the implementation changes, for example supporting 64 bits, we can change it later.

• Field's SubFieldSubtitution method now returning single value (*subField) instead of two (*subField, bool), since it will be nil anyway if no SubField is found.

• Fix on SubFieldSubtitution should have continue to lookup instead of returning when 1 single map is not match.

• Now when creating fields slice, we use fieldsArray [256]proto.Field as backing array for temporary slicing, this way we don't need to worry about component expansion re-triggering runtime.mallocgc causing performance overhead.
