pub fn build(self) -> SettingGroup

Compute the layout of the byte vector used to represent this settings group.

The byte vector contains the following entries in order:

1. Byte-sized settings like NumSetting and EnumSetting.
2. BoolSetting settings.
3. Precomputed named predicates.
4. Other numbered predicates, including parent predicates that need to be accessible by number.

Set self.settings_size to the length of the byte vector prefix that contains the settings. All bytes after that are computed, not configured.

Set self.boolean_offset to the beginning of the numbered predicates, 2. in the list above.

Assign byte_offset and bit_offset fields in all settings.
