* Offical Swift port for FlexBuffers This is the offical port for FlexBuffers within swift, and it introcudes a Common Module where code is shared between flatbuffers and flexbuffers. Writing most supported values like maps, vectors, nil and scalars into a flexbuffer buffer. And includes tests to verify that its similar to cpp * Reading a flexbuffer Implementing reading from a flexbuffer, enabling most of the buffers features, like most types, maps, vectors, typedvectors, and fixedtypedvectors. Currently, if an offset/object cant be read we default to a swift nil instead of the default flexbuffers 'null' with all values. * Fixes bazel breaking due to new project structure Address warnings within the library * Adds comment on why we added the code & properly enforce the amout of bytes needed
