Allow user defined block hooks when using two step write for selective cars

Update ipld libs

update ipld libs to fairly recent version (lastest used by go-ipld-prime-proto

Update go-ipld-prime to the era of NodeAssembler.

fix: update the cli tool's car dep

feat: move car program to a separate module

That way, this repo doesn't end up bringing in urfav/cli as a dependency.

feat: only require the NodeGetter interface instead of the DAG interface

This makes it possible to pass in a dagservice "session" for better performance
when fetching from bitswap.

feat(car): add selector support

rename SizeHeader to HeaderSize, add comments and cleanups in selective car test

convert SelectiveCarPrepared data to accessors

Allows a selective car to simply be written, or to be prepared then dumped to disk

Use an ipld.Node for a selector rather than an actual selector operation -- that way it can be
serialized as needed

when writing a car, seperate traversal of the selector from the actual writing of the Car file,
which allows us to gather information about what will be written in the car, and to dedupe writes

add ldsize function to estimate size of an LdWrite

Add a mechanism for doing CAR files that write with selectors

fix #14

don't use private types in public functions
