[go] support memberid x category filter

[yssk22]

Summary

current member filter and category filter is not so flexible and doesn't support the case when I want to see "everything" for risachi while I want to see only daily photo and FSK for yuppyon.

This change enable such a complex filter.

Test

• go test
• graphql playground

query helloprojectQuery {
    helloproject {
      elineupMallItems(params: {
        memberCategories: [
          {
            memberId:"8590783732",
            categories: [keyring_other],
          },
          {
            memberId:"8590783733",
            categories: [keyring_other],
          },
        ]
      }) {
        edges {
          node {
            id
            name
            category
            taggedMembers {
              id
              name
            }
          }
        }
      }
    }
}
