Accept access flags for allocate

[cholcombe973]

Addresses #31. Modifies accept to take an optional set of access flags. Pretty straight forward :)

Thanks for the PR! Let's add this as a new method alloc_with_permissions (or something like it), and then have the existing allocate call that one with the default flags. That way the Option isn't needed and we avoid this needing to be breaking change to the API :)

Sounds good! I'll have an update coming in a few mins

Let me know if you'd like me to adjust the documentation. I feel like maybe it's a good idea to point out what each permission flag does.

Let's also add a line after the list that point at allocate_with_permissions if users need more control 👍
