v0.3.0-jinx2

What's Changed

• Allow multi type parsing by @CohenArthur in #349
• Parse list of generic types in function declaration by @CohenArthur in #341
• Type instantiation and Function calls generics by @CohenArthur in #343
• Parse generic type declarations by @CohenArthur in #380

These PRs add the parsing of generic types in function calls, type
instantiations, function declarations and type declarations. The syntax is the
following:

type SomeType[T](member: T);
type OtherType[T, U, V](member: T, member2: U, member3: V);
func takes_generic[T](arg: T) -> T { ... }

instance = SomeType[T](member: some_argument);
takes_generic[T](some_argument);

• Enable lto on release by @Skallwar in #390

Thanks to @Skallwar, we now have LTO release builds which are much smaller than
previously. Thanks to you and @tanguysegarra 's efforts, this means we have a
1.9MB large docker image for jinko!

• Parse and instantiate empty types by @CohenArthur in #348

This enables the concept of empty-types or value-types: Types that can be instantiated,
but do not contain any fields. They provide a lot of type safety and can be optimized
and removed completely very easily. The syntax is the following:

type Empty; // declaration

e = Empty; // instantiation

They allow the Maybe type to be implemented in the following fashion:

type Nothing;
type Maybe[T](inner: T | Nothing);

They also allow the representation of enums once we have multi-types:

type Horse;
type Cat;
type Dog;

type Animal(Horse | Cat | Dog);

• Add NoReturn type by @CohenArthur in #382

• binop: Allow binary operation as boolean by @CohenArthur in #394

• Allow function calls as booleans by @CohenArthur in #383

• Remove as_bool in Instruction trait by @Skallwar in #404

Thanks to @Skallwar, it is now much cleaner to execute expressions and cast
them as booleans for if-else conditions. Since we now have a typechecker, we
can completely avoid checking the type of variables also at execution. This should speed
up the interpreter and improve safety overall.

• docker: use alpine instead of debian by @tanguysegarra in #397
• ci: add docker stage by @tanguysegarra in #398
• ci: add specific dockerhub releases by @tanguysegarra in #411
• ci: remove docker release when push to master by @tanguysegarra in #413

We now have a fantastic Dockerfile and docker image on hub.docker.com thanks to
@tanguysegarra. It is build automatically on each push to master and available as
jinko/jinko:latest.

• Add --test flag to the interpreter by @CohenArthur in #399

We can now run tests declared in a file with the test keyword! Once we have a few more
abstractions, we will be able to write testsuites entirely in jinko. What is currently
missing is an assertion library, as well as a few abstractions.

• Resolve fixed parser issues by @CohenArthur in #393
• Add Args.count() by @CohenArthur in #381
