This commit fixes a bug where the OFM zero point
would assume values outside of [0, 255] due to it's
usage as a stand-in for a bias when emulating the
TensorFlow Lite implementation of MEAN.
The solution is to adjust for the bias using an
ADD operator with the bias value as an int16 const
tensor. The 16-bit integer is needed as the bias
is 32 bits in the original implementation but can
effectively assume values in the range [-255, 255].

Previously the keep_dims or keep_num_dims attribute was not supported for Sum and Fully Connected operators and would thus crash for certain tests. With this update, the attribute is extracted correctly and saved to the optimised tflite file.

Previously the debug database lost some operators in the debug database outputs when multiple custom operators were generated by Vela.
Also, the file offsets for command streams were always 0, even for a single custom operator. This patch should rectify these problems.

When running specific networks containing LeakyReLU operators, Vela would crash when cloning an ofm of a LeakyReLU operator.
In this procedure a deepcopy usage would try to copy an OperatorInfo object, which caused an error.
This was fixed by replacing the deepcopy usage with a copy and then manually referencing new instances of sensitive variables.
