What's changed

This release focused on improving Spreet's internals. Thanks @nyurik for all the hard work.

• Breaking change: move all public identifiers to the root of the crate, e.g. spreet::error::SpreetError → spreet::SpreetError, with the exception of resvg.
• Update oxipng dependency to v9.0.0. This improves compression of PNG spritesheets without visual changes, but the PNGs won't be byte-to-byte compatible with spritesheets output by earlier versions of Spreet
• Update resvg dependency to v0.36.0
• Remove the deprecated function spreet::sprite::generate_pixmap_from_svg()
• The spreet::sprite_name function (previously available as spreet::sprite::sprite_name) now returns Result<String, Error> instead of String, and will no longer panic
• The spreet::get_svg_input_paths function (previously available as spreet::fs::get_svg_input_paths) now returns Result<Vec<PathBuf>, Error> instead of Vec<PathBuf>, and will no longer panic
