Show titles not available on MU

From #14

It would be amazing (since you are using the API) to be able to search for titles not available on MU as well. Your website is such an improvement over the regular search that I'm sure many of us would love to use it for just searching stuff in general, not just MU. I think it'd be fine for most users if one clicks an issue and instead of getting the (beloved) Marvel viewer, one just gets an "issue not available on MU".

We may be able to simply remove this line:

marvel-by-year/src/lib/api.ts

Line 134 in 76e2eaa

hasDigitalIssue: 'true',

We can test by seeing if Master of Kung Fu comics show up (since they aren't currently available on MU)
