/**
* Generates a list of unary interface signatures from strided array data types.
*
* ## Notes
*
* -   The function returns a strided array having a stride length of `2` (i.e., every `2` elements define a unary interface signature).
* -   For each signature (i.e., set of two consecutive non-overlapping strided array elements), the first element is the input data type and the second element is the return data type.
* -   All signatures follow type promotion rules.
*
* @param dtypes1 - list of supported data types for the first argument
* @param dtypes2 - list of supported data types for the output argument
* @param options - options
* @param options.enums - boolean flag indicating whether to return signatures as a list of enumeration constants
* @throws must provide recognized data types
* @returns strided array containing unary interface signatures
*
* @example
* var dtypes = [
*     'float64',
*     'float32',
*     'int32',
*     'uint8'
* ];
*
* var sigs = signatures( dtypes, dtypes );
* // e.g., returns [ 'float32', 'float32', ... ]
