/**
* Map a list of items into an object.
*
* In the following example, a list of DomainPerms like the following:
*
* ```json
* [
* {
* "domain": "example.org",
* "public_comment": "aaaaa!!"
* },
* {
* "domain": "another.domain",
* "public_comment": "they are poo"
* }
* ]
* ```
*
* Would be converted into an Object like the following:
*
* ```json
* {
* "example.org": {
* "domain": "example.org",
* "public_comment": "aaaaa!!"
* },
* "another.domain": {
* "domain": "another.domain",
* "public_comment": "they are poo"
* },
* }
* ```
*
* If you pass a non-array type into this function it
* will be converted into an array first, as a treat.
*
* @example
* const extended = gtsApi.injectEndpoints({
* endpoints: (build) => ({
* getDomainBlocks: build.query<MappedDomainPerms, void>({
* query: () => ({
* url: `/api/v1/admin/domain_blocks`
* }),
* transformResponse: listToKeyedObject<DomainPerm>("domain"),
* }),
* });
