returning bytecode by setting output_values

[john012343210]

hi ,

>>> import solcx
>>> solcx.compile_source(
...     "contract Foo { function bar() public { return; } }",
...     output_values=["abi", "bin-runtime"],
...     
... )
``` works fine

but ,

import solcx
solcx.compile_source(
... "contract Foo { function bar() public { return; } }",
... output_values=["abi", "bytecode"],
...
... )

 is not ok

Available output_values are parsed from the solc help file. For solc v0.8.11, the line is:

--combined-json abi,asm,ast,bin,bin-runtime,devdoc,function-debug,function-debug-runtime,generated-sources,generated-sources-runtime,hashes,metadata,opcodes,srcmap,srcmap-runtime,storage-layout,userdoc

No bytcode there - maybe you want bin?
