Converts a regular stream into a tagged stream.
All this block does is add length tags in regular intervals. It can be used to connect a regular stream to a gr::tagged_stream_block.
Careful: This block is meant to be connected directly to a tagged stream block. If there are blocks between this block and a tagged stream block, make sure they either don't change the rate, or modify the tag value to make sure the length tags actually represent the packet length.

static |
itemsize | Item size |
vlen | Vector length of the input items. Note that one vector is one item. |
packet_len | Number of items per tagged stream packet. One tag is written every packet_len items. |
len_tag_key | Key of the length tag. |
