Transform concatenation does not work with "--string"
Version/Dist information:
`Python 3.10.6`
`Bash v5.1.16(1)-release`
`Ubuntu 22.04`
`x86_64`

Expected behavior is achieved when reading from a python file.
`cat test.py`:
```
#!/bin/env python
test_string = 'This' + '  ' + 'may ' + ' ' +  'not' + ' ' + 'work'
```
```flynt -tc t.py```:
```
test_string = f"This may not work"
```

```flynt -tc --string "test_string = 'This' + ' ' + 'may' + ' ' + 'not' + ' ' + 'work'"```

Expected result:
```
test_string = f"This may not work"
```

Actual result:
```
test_string = 'This' + ' ' + 'may' + ' ' + 'not' + ' ' + 'work'
```

Flynt does not report any errors or missed opportunities. It is simply not recognized. Passing it in from an array, using < <(...) , with escaped double quotes, etc., still does not produce the expected behavior.
