Improve Julia language support

[hatemhosny]

Julia language support is provided by @chriskoch/julia-wasm, which is based on julia-wasm.

Currently, this package contains a WASM compiled version of the Julia 1.04 compiler. It does support the standard library or using external libraries.

julia-wasm repo has not been active over the past few years.

Proposed improvements:

• Update the wasm compiler to the latest Julia compiler (preferably with an automated script that allows future updates)
• Allow using the standard library
• Think about a way to support popular external libraries (may be similar to Pyodide or WebR)
