Tidy up `createTempCam()`
Add `loadLocation()` and `clearLoadLocation()` functions
Add `renderTime` variable for `stopTempCam()`
Add wrapper functions for each one (for my own sanity):
`createCam()` = `createTempCam()`
`startCam()` = `startTempCam()`
`stopTempCam()` = `stopTempCam()`
- Allows filters to be applied to custom cameras when running `startTempCam()`
- Automatically interpolates between cameras created in the same script
- Toggle to attempt to render the location if camera is far away from the ped
- Clears all created cameras when `stopTempCam()` is run
