Simpler dependency management

[aminya]

Based on what is suggested in JuliaLinearAlgebra/MKL.jl#19 (comment) by @KristofferC:

Use this way: https://github.com/JuliaSparse/Pardiso.jl/blob/81c8391e86cebaf71e936363664d878b22b1fd9a/src/Pardiso.jl#L37-L43.

There is nothing you need to do with this package here. Just depend on MLK_jll and do something like: https://github.com/JuliaSparse/Pardiso.jl/blob/81c8391e86cebaf71e936363664d878b22b1fd9a/src/Pardiso.jl#L25-L27 together with https://github.com/JuliaSparse/Pardiso.jl/blob/81c8391e86cebaf71e936363664d878b22b1fd9a/deps/build.jl#L67-L83.

We can use MKL_jill to provide the libraries.

I can see if I can get this working with MKL_jll later tonight.

This is essentially already in #33 and firmly on my list of ToDos.
Two points here:

1. The reason why I have not started on using MKL_jll is that this would break the version for Julia <1.3 (as far as I understand). I was still thinking about maybe tackling a few of the other issues first, so that they are also available for older Julia versions.
   Unfortunately I had to catch up on research and this package is working as it is.
2. I use this package mainly to learn things about Julia and SW development, and getting started on this something I am quite looking forward to. Therefore, if you think that moving to artifacts is important, I would not be sad to have a go at it first. I really appreciate the assistance, and might still need it, but I was quite looking forward to this one.

There is no issue regarding that. Older Julia users can use the current version of IntelVectorMath!

My point is that maybe #20 or #22 should be tackled first, so that they are in the version that older julia users can use.

Sure, just ping me if you run into problems and maybe we can figure it out together.

I just had a chance to take a look, and it seems that MKL.jll does not export libmkl_vml_avx2, which is the library that is being ccalled here.
Will update once I know what do about it.

We can address #20 but, #22 doesn't have a solution for now.

#39 now implements this.

#39 is now merged and about to be registered
