gives True if the ByteArray object ba might be imported as format "fmt" and gives False otherwise.
Details
- ByteArrayFormatQ attempts to identify whether a ByteArray object can be imported as a specific format.
- ByteArrayFormatQ uses heuristic methods and may not give correct results, particularly for shorter arrays.
- ByteArrayFormatQ does not verify that ImportByteArray would succeed if applied to ba.
