fix qasm to yao translation

[GiggleLiu]

Changes

• new yao APIs MEASURE, RESET and Barrier
• fix qreg address translation
• fix function translation

Notes

• the 3rd parameter of MEASURE should be a view of classical register, like view(c, [2,3]), is this possible?
• one of your test is broken. @thautwarm

Now the following example works perfectly, isn't this amazing @Roger-luo @wangleiphy

julia> src1 = """
       OPENQASM 2.0;

       gate cu1(theta) a,b
       {
           U(0,0,theta/2) a;
           CX a,b;
           U(0,0,-theta/2) b;
       }

       qreg q[3];
       qreg a[2];
       creg c[3];
       creg syn[2];
       cu1(pi/2) q[0],q[1];
       """
"OPENQASM 2.0;\n\ngate cu1(theta) a,b\n{\n    U(0,0,theta/2) a;\n    CX a,b;\n    U(0,0,-theta/2) b;\n}\n\nqreg q[3];\nqreg a[2];\ncreg c[3];\ncreg syn[2];\ncu1(pi/2) q[0],q[1];\n"

julia> circ = @eval $(trans(parse_qasm(lex(src1))))

can you fix the CI? @GiggleLiu the PR looks good in general. I'd like to merge it and register the package first.
