[ISSUE]

**Title:** Incorrect `bands` Attribute for `'I;16'` Image Modes Causes Test Failures

**Description:**
When handling image modes like `'I;16'`, the `bands` attribute is incorrectly set as a string instead of a tuple. This leads to assertion failures in tests and may affect image processing functionalities.

**Example Buggy Code:**
```python
from PIL import ImageMode

# Attempting to retrieve mode information for 'I;16'
mode_info = ImageMode.getmode('I;16')
print(mode_info.bands)  # Output: 'I' instead of ('I',)
```

**Expected Behavior:**
The `bands` attribute should be a tuple containing the band names. For `'I;16'` and similar modes, it should return `('I',)`.

**Actual Behavior:**
The `bands` attribute incorrectly returns a string `'I'` instead of the expected tuple `('I',)`.

**Impact:**
This incorrect attribute type causes tests that expect a tuple to fail, such as:
```python
m = ImageMode.getmode('I;16')
assert m.bands == ('I',)  # This assertion fails because m.bands is 'I'
```
Additionally, it may lead to unexpected behavior in image processing functions that rely on the `bands` attribute being a tuple.

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.

Please first localize the bug based on the issue statement, and then generate *SEARCH/REPLACE* edits to fix the issue.

Every *SEARCH/REPLACE* edit must use this format:
1. The file path
2. The start of search block: <<<<<<< SEARCH
3. A contiguous chunk of lines to search for in the existing source code
4. The dividing line: =======
5. The lines to replace into the source code
6. The end of the replace block: >>>>>>> REPLACE

Here is an example:

```python
### mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
```
</solution>

Please note that the *SEARCH/REPLACE* edit REQUIRES PROPER INDENTATION. If you would like to add the line '        print(x)', you must fully write that out, with all those spaces before the code!
Wrap each *SEARCH/REPLACE* edit in a code block as shown in the example above. If you have multiple *SEARCH/REPLACE* edits, use a separate code block for each one.
