tengen (development version)

breaking: the DataType hierarchy (BooleanType(), IntegerType(), UIntegerType(), FloatType()) is replaced by a single enum-style DataType with one singleton object per dtype (adds f16, bf16, and c64/c128). Construct dtypes with as_dtype().
breaking: renamed ndims() to naxes().
new: dtype_width() and dtype_category() to inspect a DataType.
new: the predicates is_dtype_float(), is_dtype_int(), is_dtype_uint(), is_dtype_bool(), and is_dtype_complex().
as.character() is now a single method on DataType and returns the canonical dtype string; "i1" and "pred" are accepted as aliases for "bool" in as_dtype().
The package now requires R (>= 4.2.0).

Added the DataType class hierarchy: BooleanType, IntegerType, UIntegerType, and FloatType with ==/!= comparison, print(), and as.character() methods.
Added as_dtype() generic to convert strings (e.g. "i32", "f64") to DataType objects.
Added is_dtype() and assert_dtype() helpers for type checking.
Added nelts() generic to get the number of elements of a tensor.
Renamed TensorDataType to DataType.
