requests module requirement is missing

Describe the bug

TL;DR Python "requests" module requirement is missing,

See the patch at the bottom of the issue just to save time: 0001-we-get-Missing-requests-module-update-README.md-install.patch.txt

What follows is a somewhat long user report, just in case someone else is stumbling on this, and, it saves its time. In the end we-get is working, so there's a happy ending.

Thanks!

To Reproduce

The next steps detail more or less the steps and actions performed to get we-get working:

Follow the README.md install instructions: The setup.py is nowhere to be found:

Installation
=========
run from the root folder
.. code-block:: bash
$ python3 setup.py install
python3: can't open file 'setup.py': [Errno 2] No such file or directory

No problem, follow the standard PEP517 build:

pip3 install --user build # install the build PEP517
python3 -m build .        # build from sources
pip3 install --user dist/we-get.tar.gz

Run the we-get tool we just installed into $HOME/.local/bin
```
$HOME/.local/bin/we-get -s ubuntu
# error: Cannot find target 'yts'.
```
But the yts module is there and correctly loaded. Go ahead, and have a look at the source code.

The [we_get/core/we_get.py] hides the exception error when importing modules. So change we_get.py to see the exception:

diff --git a/we_get/core/we_get.py b/we_get/core/we_get.py
index 39ede99..3c40eec 100644

Re-run the we-get tool:

$HOME/.local/bin/we-get -s ubuntu
# Cannot find target 'yts'....
# error: <class 'ModuleNotFoundError'>
# No module named 'requests'

Bummer. So add the missing "requests" to pyproject.toml.

Then, build and install again from source, to ensure requests module is installed.

Check again, to see if we-get is working:

~/.local/bin/we-get -s ubuntu-20
# Fetching data from <target> ...
<target> Ubuntu Server 20.04.1 LTS  Raspberry Pi 3 64-bit [2/0] 

# That's GREAT!
