built-in batches (like byte alignment)

[hello-adam]

The Take Skip plugin is flexible enough to do alignment, but it is tedious to manually perform 7 different take skip operations to perform a common task such as byte alignment.

Rather than making an alignment plugin, built-in batches could be included to perform the various sXt* operations of a byte alignment. This will avoid the need for a new plugin and will leverage some conveniences of batches like automatic multi-threading of separate operations.

this is in 0.53.0 - more built-in batches might be useful down the line, but they should be trivial to add now.
