**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Currently, the decimal array builder use `FixedSizedListBuilder`. This is not a good solution because: 1. `DecimalArray::from_fixed_size_list_array` is a “dangerous” function: The null buffer of the child data is dropped. 2. More space is occupied: To build a fixed size list array, we have to create another child array data. But what we need is just the value buffer **Describe the solution you'd like** - [ ] add new function DecimalArray::from_fixed_size_binary_array` - [ ] Update the decimal builder to use `FixedSizedBinaryBuilder` - [ ] **Optional**, deprecate `DecimalArray::from_fixed_size_list_array` **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
