Release new version with updated eosio

[kjg]

Hi,

I'm trying to update my ual-anchor dependencies, and the latest version pulls in @greymass/eosio@0.5.2. However iit also depends on this package in which the latest release still pulls @greymass/eosio@0.4.9.

I see that 4643ef9 does update eosio to 0.5.x, so it would be great if you could release a new version to npm so that we don't need pull in two versions of @greymass/eosio

Thanks!
