Align with upstream JTS 1.18+

[bjornharrtell]

JSTS is currently based on JTS 1.17.x. Since then there has been two feature releases of JTS, 1.18 and 1.19.

It's unfortunately a non trivial effort to update because the new things coded in JTS uses features of Java that my transpiler (https://github.com/bjornharrtell/java2estree) currently cannot handle.

I also carry several patches on JTS 1.17.x to make it work currently which further complicates this.

@willcohen Nice work! I look forward to seeing some visual demos.

[bjornharrtell]

@willcohen looks very interesting! I very much support your initiative and hope to try it out soon. ❤️

To be clear, I estimate this will need somewhere around two weeks full time work and I do not feel a pressing need to invest my free time into it at this time.

@dr-jts and @bjornharrtell -- visual demos onto maplibre now available on the demo page: https://willcohen.github.io/wasmts/
