Thanks for bringing this up - I think it's definitely in scope to add a
decimal extractor and appender. We'd probably need a struct to define a
decimal...maybe:
```c
struct ArrowDecimal {
// Words defined from most-significant to least-significant or the other
way around?
// nanoarrow could take care of ensuring that these are copied in the
right order on big endian
int32_t words[8]; // or int64_t words[4]?
int32_t precision;
int32_t scale;
};
ArrowErrorCode ArrowArrayAppendDecimal(struct ArrowArray* array, struct
ArrowDecimal* value);
void ArrowArrayViewGetDecimal(struct ArrowArrayView* array_view, struct
ArrowDecimal* out);
```
Do we need creation to/from `double`?
