feat(Antiban): Add MsUntilBreak, and MsUntilSleep AntiBan helpers

[BaldPRs]

Problem:

TimeUntilBreak is awkward for programmatic use. It returns a formatted string, which is useful for logging but requires parsing to use in logic. To retrieve the MS until an antiban sleep or break you have to use something similar to the example code which is difficult to read, and mentioned nowhere in the docs.

Suggestion:

Add two helper functions that return the raw milliseconds until the next scheduled break/sleep (if one exists):
MsUntilBreak(): Double
MsUntilSleep(): Double

Example Before:

{$I WaspLib/osrs.simba}

begin
  if ((Length(Antiban.Breaks) > 0) and (Antiban.Breaks[0].Next - GetTimeRunning() < Random(140, 240) * ONE_SECOND)) or
     ((Length(Antiban.Sleeps) > 0) and (Antiban.Sleeps[0].Next - GetTimeRunning() < Random(140, 240) * ONE_SECOND)) then
    WriteLn('Break coming soon!');
end;

Example After:

{$I WaspLib/osrs.simba}

begin
  if (Antiban.MsUntilBreak() < Random(140, 240) * ONE_SECOND) or
     (Antiban.MsUntilSleep() < Random(140, 240) * ONE_SECOND) then
    WriteLn('Break coming soon!');
end;

Use Case

A Scripter wants to clean up or perform specific actions before a break interrupts execution. This helper now allows the scripter to perform a simple MS comparison against the upcoming break/sleep.
