TA-Lib

Somehow `import talib` (see [TA-Lib](https://github.com/mrjbq7/ta-lib)) gives me

```
TA_Lib==0.4.17
talib==0.1.1
```

where the first one is fine, while the second one seems to be nonsense as it results in error upon installation:

```

Shall this be blacklisted?

Start by reproducing the reported `import talib` dependency resolution and trace how pipreqs maps that import to a package name. Check the existing import-to-package handling and blacklist data, if present. Done means the generated requirement selects TA-Lib rather than the unrelated `talib` package, with the reported installation failure covered by a regression check.
