Merge branch 'develop-remove-ifelse' into develop. Close nasa#150.

**Description**

The dependency on `IfElse` is quite unnecessary: it seems like the only
function we use from that library is `awhen :: Monad m => Maybe a -> (a
-> m ()) -> m ()`, which is a type-specialized version of
[`Data.Foldable.for_`.](https://hackage.haskell.org/package/base-4.20.0.1/docs/Data-Foldable.html#v:for_).
Since the latter is in `base`, we can simplify Ogma by removing the
dependency on `IfElse`.

**Type**

- Management: Reduce technical debt, in compliance with style guide.

**Additional context**

None.

**Requester**

- Ivan Perez

**Method to check presence of bug**

The following dockerfile checks that no cabal package depends on IfElse,
in which case it prints the message "Success":

```Dockerfile
FROM ubuntu:focal

RUN apt-get update

RUN apt-get install --yes git

SHELL ["/bin/bash", "-c"]
CMD git clone $REPO \
    && cd $NAME \
    && git checkout $COMMIT \
    && ! grep -niHre 'IfElse' --include='*.cabal' ogma** \
    && echo "Success"
```

Command (substitute variables based on new path after merge):

```sh
$ docker run -e "REPO=https://github.com/NASA/ogma" -e "NAME=ogma" -e PAT="ogma-" -e "COMMIT=<HASH>" -it ogma-verify-150
```

**Expected result**

Running the dockerfile above prints the message "Success", indicating
that IfElse is not required by any library in ogma.

**Solution implemented**

Replace calls to `awhen`, from IfElse, with calls to `for_`, from
Data.Foldable.

Remove the dependency on IfElse from all cabal files.

**Further notes**

None.
