Version 0.3 (#18)

## 0.3.0

### Added

- Added `vello_svg::Error`, which is returned by new functions that read
text into a `usvg::Tree`.
- Added `vello_svg::render`, which takes an svg string and renders to a
new vello scene.
- Added `vello_svg::append`, which takes an svg string and renders to a
provided vello scene.
- Added `vello_svg::append_with`, which takes an svg string and renders
to a provided vello scene with and error handler.
- Added `vello_svg::render_tree`, which takes a usvg::Tree and renders
to a provided vello scene with and error handler.

### Changed

- Updated to vello 0.2
- Renamed `render_tree` to `append_tree`
- Renamed `render_tree_with` to `append_tree_with` and removed the
`Result<(), E>` return type for the error handler.
