Add feature for FP constants to be used in functions

[prkrtg]

If you have a WAVEFORM defined using a floating point constant, we should have the ability to use that constant when generating the ACF

Example output from building deimos:

WAVEFORM testConst {
 0: SET RG_CLOCKS TO sci_llel_high, FAST;
  .+1us: RETURN;

}

Outputs to

STATE1\NAME=STATE001
STATE1\MOD1=",1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1"
STATE1\MOD2="sci_llel_high,1,0,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1"
STATE1\MOD3=",1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,,1,1,sci_llel_high,1,0"
STATE1\MOD12="1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1"
STATE1\MOD4="0,1,0,0,1,0" 
STATE1\CONTROL="0,3F"
STATE1\MOD9="0,1,0"
STATE1\MOD10="1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,1,0"

I have written you into my will

LGTM I think this means the constants have to be defined physically before their use. But that's not too big of a limitation we already have to do that with params (though it's not required by the Archon)
