This change allows token and node enums to be used outside of internal parsing by exposing them in the main public API rust_norg, thus allowing them to be used for external parsing based on the chumsky parser. For example, to create a Norg -> HTML parser.
Any suggestion is welcome :)
Dummy example code for headers and paragraphs w/ preview
```rust
use rust_norg::{parse, ParagraphSegmentToken, NorgASTFlat};
trait NorgToHtml {
fn to_html(&self) -> String;
}
fn paragraph_to_string(segment: &[ParagraphSegmentToken]) -> String {
let mut paragraph: String = "".to_owned();
segment.iter().for_each(|node| match node {
ParagraphSegmentToken::Text(s) => paragraph.push_str(s),
ParagraphSegmentToken::Whitespace => paragraph.push(' '),
ParagraphSegmentToken::Escape(c) => paragraph.push_str(&c.to_string()),
ParagraphSegmentToken::Special(c) => paragraph.push_str(&c.to_string()),
});
paragraph
}
impl NorgToHtml for NorgASTFlat {
fn to_html(&self) -> String {

NorgASTFlat::Heading {level, title, ..} => {
let mut heading_tag: String = "<".to_owned();
match level {
1 => {
heading_tag.push_str("h1>")

let heading_title = paragraph_to_string(title);
