Rename main class from `IOSSecuritySuite` to `SecuritySuiteiOS`

[DevAgani]

Fixes : #90

Proposal, rename the IOSSecuritySuite to SecuritySuiteiOS to ensure that the library name doesn't clash with the Main class. This is an extreme approach, but has benefits

• Users of the library will only need to update the places where they're calling the library
• Decided to and the suffice iOS to indicate that this set of Security features are available for iOS

So instead of

if IOSSecuritySuite.amIJailbroken() {
    print("This device is jailbroken")
} else {
    print("This device is not jailbroken")
}

Becomes

if SecuritySuiteiOS.amIJailbroken() {
    print("This device is jailbroken")
} else {
    print("This device is not jailbroken")
}

On the extreme end, this will be a breaking change, so it means this needs to be handled with extreme care.

Sorry, I'm not going to change this library name because of a Swift compiler bug that's already being fixed and rarely happens.
