Weave strings together

Given a list of strings(and optionally, their length) as input, weave the strings together.

# Intro
Your goal is to mimic the [`WV` operator in Pip](https://dloscutoff.github.io/pip/operators). Take a list of strings and alternate between their characters like so:

```
hello,
world, → hwc,eoo,lrd,lle,od → hwceoolrdlleod
code
```

Effectively, you need to group the characters at each index, and join them into a single string.

No truncation should be done, and all the characters of each string must be used.

```python
["kino","cinema","movie"] → kcmiionnvoeimea
["code","golf"] → cgoodlef
["Hi","","There"] → HTihere
["Explanation"] → Explanation
```
