Add option for disabling tests

[data-man]

Also I propose rename test directory to tests.

[kelson42]

@data-man Which commands exactly run the tests and for which you would like to have a variant which would not?

[data-man]

I'm currently commenting out subdir('test') in meson.build for speed up compilation.

tests are not executed by running:

meson . build
ninja -C build

like written in the README.md, so I don't understand the problem.

[data-man]

I don't understand the problem.

Problem is slow compilation.

[kelson42]

@data-man Please give me clear reproduction steps, what it does and what you expect to be done.

[data-man]

meson . build
ninja -C build

ninja: Entering directory `build' [0/133] ...

After commenting out subdir('test') in meson.build:

ninja: Entering directory `build' [1/46] ...

I don't want to compile unnecessary files.

Got it! Makes sense, would you be able to make a PR tackling the two points you have reported?
