Invoking the @EventBusSubscriber.Condition method suffered from the same reflection problems as described in #80, which is that it will have to load the entire method table including parameters classes that might not be present.

Having to dynamically invoke a given method without reflection only leaves a few options, which are either using MethodHandle which are generally faster than reflection if invoked a ton of times but significantly slower if only invoked once
or using the semi-obscure LambdaMetafactory api. This generates a synthetic anonymous class that implements a functional interface to get a value from the specified method, while that might sound like it would be a lot slower than reflection it was in fact consistently faster and doesn't have to load the entire method table.

Makes @EventBusSubscriber's able to be registered during earlier init phases as some events are fired during pre-init, specifically some of the registry events. This means that if an @EventBusSubscriber wants to listen to that event and potentially pick up something that gets fired during the pre-init phase of a mod that loads earlier than NHLib, it would have to be registered during the construction phase. This is only applicable in very few cases but I thought it'd be best to at least make it an option.

Also some different minor improvements like using ASMDataTable.getAll to get the side-only classes instead of ASMDataTable.getAnnotationsFor. This alone lowered the time it took for that part of the pre-proccesing from ~90ms to ~5-15ms on my GT5U test branch, and that was while only ever using ASMDataTable.getAnnotationsFor twice...
