Crashes if CiviMember disabled
See https://civicrm.stackexchange.com/questions/45352/membershiprenewallink-cant-find-membershiptype
I think it should be pretty obvious to most people that CiviMember is required to use this extension, but it would be nice to mitigate the hard-crash caused by PHP class-not-found at https://lab.civicrm.org/extensions/membershiprenewallink/-/blob/main/settings/membershiprenewallink.setting.php#L11
Once the core version requirement is up to 5.63, you can add this to the info.xml:
<requires>
<ext>civi_member</ext>
</requires>
That probably wouldn't eliminate every crash scenario but at least it would be semantically correct to declare that dependency.
