I used the name matmultay! to still allow LinearAlgebra.mul! to work, but it admitedly is awful. Other suggestions @LuEdRaMo ?

Coverage is 92.023% — lb/mul!_matrix into master. No base build found for master.

Other taylorized methods in TS do not use the suffix tay, e.g., add!, subst!, mul!, div!, etc. So, I would suggest to simply call the function matmul!. I believe there is no LinearAlgebra.matmul! and, even if it were the case, the should not be a problem as long as TS does not export that name.

There s no matmul! indeed... ok, let's use it.
