Adds a deletion vector writer and related helper classes, as part of work to expose writing deletion vectors in the Kernel.

• Adds a trait for DeletionVector and a default implementation that is backed by a RoaringTreemap.
• Adds a DV Writer that can write multiple DVs to a single file.
• Adds a first class concept for DeletionVector path that can be used to generate either the absolute path or the encoded relative path. This is used to give back a location to writers that want to write new DVs, and then create new DeletionVectorDescriptor objects that combine the offsets.
• To facilitate testing, updated DeletionVectorDescriptor to have a read method that supports validating CRC while reading the deletion vector.

TESTING=Verified both values written directly, and round tripping with DeletionVectorDescriptor for reads.
