Port to Clash 1.4.2
Would be a shame to let this bit-rot. It passes all the tests when I run stack run.
make doesn't work with my versions of yosys, arachne-pnr, and the icestorm tools though.
$ yosys -V
Yosys 0.7 (git sha1 61f6811, gcc 6.2.0-11ubuntu1 -O2 -fdebug-prefix-map=/build/yosys-OIL3SR/yosys-0.7=. -fstack-protector-strong -fPIC -Os)
$ arachne-pnr -v
arachne-pnr 0.1+20151224git1a4fdf9 (git sha1 1a4fdf9, g++ 6.2.0-10ubuntu1 -O2 -fdebug-prefix-map=/build/arachne-pnr-8ETCVz/arachne-pnr-0.1+20160813git52e69ed=. -fPIE -fstack-protector-strong)
First I have to do:
diff --git a/rtl/syn/icoboard.pcf b/rtl/syn/icoboard.pcf

but after fixing that I get problems where the BRAM content generated by cfm-as is "too small":

Alright, turns out the issue was just my "ancient" versions of all the tools. I've just upgraded to the latest HEADs of the github repo's:
christiaan@DESKTOP-O5QKI8I:~/cfm$ yosys -V
Yosys 0.9+4081 (git sha1 83a21814, clang 6.0.0-1ubuntu2 -fPIC -Os)

arachne-pnr 0.1+328+0 (git sha1 c40fb22, g++ 7.5.0-3ubuntu1~18.04 -O2
And make all gets through to the end.
