Updated hash methods and support python version 3.10

• Python versions available have been shifted from [3.6 to 3.9] to [3.7 to 3.10] to support the latest version.
• The hash class now relies on the loaded label map to determine how to convert a string into a hash. If a label isn't found, it falls back to the regular algorithm.
• You can also use the hash.set_strict(true) method to change the fallback behavior, and throw an error if the label is not found. This might help a user to catch typos in label names.
• With the hash.algo("my_string") method, you can use the hash40 algorithm directly and skip label lookups. You probably will not need to use this unless you are using the strict flag.

0.3.0

• Before, the mutate method would simply redefine the pointer associated with a variable, but not change underlying values of the original pointer. Clearly I didn’t test this well enough because I expected it to rewrite params entirely.
• The ‘mutate’ method has been removed and replaced with several new methods, one for each possible param type: ‘set_bool’, ‘set_i8’, etc. This functions similarly to the param constructors, but it operates on existing param objects. Just provide a value to set the param to. Since most params are alterable by value, this allows you to also change the type of a param, or to change list/struct params after altering them via separate data structures

0.2.0

‘hash’ class changes:

• hash.value now returns the integer representation always
• str(hash) now returns the string representation without any prefix
  • before: ‘hash (“param_name”)’
  • after: “param_name”
  • repr(hash) still returns the former representation

‘param’ changes:

• You can now retrieve length of param structs and lists directly with len(param)
• You can now mutate a param‘s identity with the param.mutate method. Whereas in order to do this previously, you would need to access the parent and reassign this param to a new one, you can now do it with a direct reference. This allows you to convert list or struct params to an intermediate form (lists or dicts), edit them, then modify the base param without going through its parent
