Add support for setting cs_flags and update workspace

[pmarkowsky]

This PR adds support for setting the limited set of cs flags that you can via csops.

e.g.

$  sudo ./target/debug/csops-bin status 826                 
PID: 826 cs_flags: 637623057; CS_VALID ; CS_FORCED_LV ; CS_HARD ; CS_KILL ; CS_RESTRICT ; CS_ENFORCEMENT ; CS_ENTITLEMENTS_VALIDATED ; CS_RUNTIME ; CS_NO_UNTRUSTED_HELPERS ; CS_PLATFORM_BINARY ; CS_SIGNED 
[ user@Mac (10:40PM) ~/src/csops-rs  ]                                                                             
$  sudo ./target/debug/csops-bin -v 0x00400000 set-status 826
