### Bug fixes

Fix a bug that prevented balancing of repeat nodes when there were skipped nodes present between the repeated elements (which ruined the efficiency of incremental parses).

### New features

`TreeBuffer` objects now have an `iterate` function.

Buffers can optionally be tagged with an (unnamed) node type to allow reusing them in an incremental parse without wrapping them in a tree.

### Breaking changes

`Tree.build` now takes its arguments wrapped in an object. It also expects the buffer content to conform to from lezer 0.7.0's representation of repeated productions.

The `repeated` node prop was removed (the parser generator now encodes repetition in the type ids).
