saxon 3bb1ca9379 stream/mts: wrote NewMeta func to initialize map in the Meta struct. Also wrote two tests, one TestAddAndGet to see if we can add and get metadata, and also second TestUpdate to see if we can correctly update metadata with the same key using Meta.Add 2019-01-27 17:57:42 +10:30

saxon 9171b56d31 stream/mts: created new type to represent Descriptor (typedef of []bytes) so that we can create receiver functions. Wrote AddDescriptor func to add or update a descriptor in a pmt. Wrote ProgramInfoLen func to return the program info length i.e. len of descriptors. Wrote HasDescriptor to check if descriptor exists, if so return the descriptor so that we can update. Wrote descriptors which returns []byte of all descriptors. Wrote create descriptor, which adds a descriptor to the existing if any i.e. shifts data downwards to accomodate new data. Wrote update func to update a descriptor. 2019-01-27 16:55:00 +10:30
