Frame addresses are only used in the context of configuration frames.
Remove the prefix to reduce typing that does not improve clarity.

There seem to be 2 frames of padding between rows in a bitstream. For
single-frame writes, these are parsed as type 0 packets and ignored.
Normal bitstreams use a single FDRI write that apparently includes this
padding and needs to be ignored in the auto-increment handling.

MemoryMappedFile's data() method returns a void* as it has no idea what
type the contents are. Viewing it as bytes is a very common operation
so add a convience method that wraps the pointer in a Span<uint8_t>.

Type 2 packets are used for when the amount of data required exceeds the
word count field in a Type 1 header. ConfigurationPacket mostly hides
this detail from the user but occasionally it is handy for debugging.

Both ConfigurationPacket and Configuration need to reference registers.
Use a common scoped enum to reduce change of errors. Leverage stream
operator to simplify outputing register names.
