Adds array support - previously only slices were supported.
Adds new test cases for multidimensional arrays and slices.
All previous test cases are unmodified and passed (fully backwards compatible).
Removes hard-coded type conversions for arrays, instead now relies on the type support of the array element's type conversion support.
Less maintenance for arrays, new type conversions are automatically supported when array's element gains new type support.
Simplifies typed_array_gen.sh generator script by removing the hard-coded single-dimensional types for arrays.
Only typed_array.go.erb and typed_array_gen.sh have been changed + 1 new auxiliary function in array.go file + additional tests in test files for each array. Other changes are from generated code.
Methods defined on T are also available on *T. Thought this technically
changes the interface, because *T will be automatically dereferenced as
needed it shouldn't be a breaking change.
See a8802b16cc for similar change.
typed_array.go.erb was not updated back in
a8802b16cc when Value, EncodeBinary,
EncodeText, and MarshalJSON were changed to be defined on T instead of
*T. This has been corrected.
