Use sbt-projectmatrix to publish unique artifact names for each version of slick for the same cats version (that's binary compatible)

So this creates this set of project verions:

[info] 	   docs
[info] 	 * root
[info] 	   slickcats-slick3-3
[info] 	   slickcats-slick3-32_12
[info] 	   slickcats-slick3-4
[info] 	   slickcats-slick3-42_12
[info] 	   slickcats-slick3-5
[info] 	   slickcats-slick3-52_12
[info] 	   slickcats-slick3-53

This maps to:

com.rms.miu:slickcats-slick3-3_2.12:0.10.6
com.rms.miu:slickcats-slick3-3_2.13:0.10.6
com.rms.miu:slickcats-slick3-4_2.12:0.10.6
com.rms.miu:slickcats-slick3-4_2.13:0.10.6
com.rms.miu:slickcats-slick3-5_2.12:0.10.6
com.rms.miu:slickcats-slick3-5_2.13:0.10.6
com.rms.miu:slickcats-slick3-5_3:0.10.6

so you get a:

  "com.rms.miu" %% "slickcats-slick3-3" % "0.10.6", // 2.12/2.13
  "com.rms.miu" %% "slickcats-slick3-4" % "0.10.6", // 2.12/2.13
  "com.rms.miu" %% "slickcats-slick3-5" % "0.10.6" // 2.12/2.13/3.3.x (LTS)
