rust parser: MarkdownCursor is missing several methods compared to TreeCursor

[janWilejan]

tree-sitter-md = { version = "0.3.2", features = ["parser"] }

The documentation for MarkdownCursor says

This exposes the same methods as TreeCursor, but abstracts away the double block / inline structure of MarkdownTree.

But MarkdownCursor is missing several methods that TreeCursor has. Namely:

pub fn depth(&self) -> u32
pub fn descendant_index(&self) -> usize
pub fn goto_last_child(&mut self) -> bool
pub fn goto_descendant(&mut self, descendant_index: usize)
pub fn goto_previous_sibling(&mut self) -> bool
pub fn reset(&mut self, node: Node<'cursor>)
pub fn reset_to(&mut self, cursor: &Self)

Also MarkdownCursor does not implement Clone. It should implement Clone.
