Use the libzim.a generated by kiwix-build

[mossroy]

The Makefile could be modified to take a provided libzim.a (from the CI), instead of recompiling it from scratch

Beware of the potential issues that could happen if different versions of emscripten are used to compile libzim.a and this Makefile

[Jaifroid]

Some useful information for testing the build failures when building with libzim.a and dependencies from kiwix-buils:

• Build failures with Emscripten image > 3.1.12 (when building from source) #9 (comment)
• Segfault with published wasm version of libzim libzim#751

In short, they appear to build correctly, but we are getting index and memory out of bounds errors in the console.log when using the WASM.

@kelson42 If we have stable nightly and release builds of the libzim WASM binaries, as it seems we will from openzim/libzim#751, I'll be happy to work on this issue. But to do so, I need to merge #14, so that I'm not mixing up the issues in one enormous PR, and to keep the commit history logical. Could you kindly approve #14 so that I can continue (I could do some work on this on Thursday)?

[kelson42]

@mgautierfr Please make a new build of libzim so @Jaifroid can benefit of a stable version and not rely anymore on any nightly here.

@Jaifroid Release has been done again. https://download.openzim.org/release/libzim/libzim_wasm-emscripten-8.1.0-1.tar.gz

Should be good now.

Excellent, I'll get to it.

@mgautierfr You'll be pleased to know that this Repo is now building nightly versions based on the nightly wasm binaries provided by kiwix-build, e.g. https://download.openzim.org/nightly/2022-12-13/, and also that the default for a Release build is to use the latest released binaries from kiwix-build.

Thank you very much for all your hard work and collaboration that made this possible. 😊 I've released v0.1 based on latest kiwix-build release.

I've retained the ability to build everything from source for reasons of troubleshooting and customization (especially relating to #17 and #11).

@mgautierfr @Jaifroid Pretty glad to see this finally happening. Kudos to both of you and @mossroy and @dattaz for the initial push.
