Fix generated IconData body for SVGs containing #

[sonicjhon1]

Summary

This PR fixes icon code generation for SVG content that contains sequences such as "#fff".

Previously, generated icon bodies used r#"... "# raw string literals. SVG attributes like fill="#fff" contain the "# sequence, which prematurely terminates the raw string and causes the generated Rust code to fail to compile.

The generator now emits icon bodies using r###"..."###, preventing conflicts with common SVG attribute values.

Changes

• Change generated IconData body literals from r#"... "# to r###"..."###
• Add logos:chrome to the integration test suite as a regression test
• Verify generated code compiles successfully when SVG content contains color attributes such as fill="#fff"

Example

Before:

body: r#"<path fill="#fff" />"#,

After:

body: r###"<path fill="#fff" />"###,

Testing

• Updated test_generated_code_compiles
• Added logos:chrome, which contains SVG attributes that previously triggered the issue
• Confirmed generated code compiles successfully

Closes #12

Code Review

This pull request updates the generated icon body string delimiter in src/generator.rs to use three hash marks (r###"..."###) instead of one, and adds integration tests for the logos:chrome icon. However, changing the raw string delimiter breaks the parser in extract_raw_string_value which specifically looks for r#" and "#. The parser needs to be updated to support the new delimiter or dynamically handle the number of hash marks.
