Create a customized argon2i instance

For all arguments, there are default values present in superclass to be used if not all values need to be customized

Parameters:

memoryCost - the memory cost in kibibytes

parallelism - the amount of threads to use

timeCost - the amount of iterations to use

saltLength - the length of the generated salt

hashLength - the output length for the hash

Returns:

the customized argon2i instance

Throws:

InvalidHashException - if any of the parameters are invalid
