provide map.entries entry mapper functions with reference to functor being mapped

update map.entries synopsis

```
* type EntryMapper = (
* entry [key string|any, value any],
* ftor FunctorWithEntries
* )=>Promise|[resultKey string|any, resultItem Promise|any]
```

update docs

```
* If the functor is a map:
*
* ```coffeescript [specscript]
* mapper(entry [key any, value any], ftor Map) -> resultEntry Promise|[
* resultKey any,
* resultValue any,
* ]
* ```
*
* If the functor is an object:
*
* ```coffeescript [specscript]
* mapper(entry [key string, value any], ftor Object) -> resultEntry Promise|[
* resultKey string,
* resultValue any,
* ]
* ```
```
