We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
[ISSUE]
**Title:** Save Handlers for BUFR, GRIB, and HDF5 Stubs Not Recognized

**Description:**
When attempting to save images using the BUFR, GRIB, or HDF5 stub plugins, an `OSError` is raised indicating that the respective save handler is not installed, even after registering a handler.

**Example Buggy Code:**
```python
class TestHandler:
    def save(self, im, fp, filename):
        pass

BufrStubImagePlugin.register_handler(TestHandler())
with Image.open(TEST_FILE) as im:
    im.save("temp.bufr")
```

**Expected Behavior:**
The image should be successfully saved using the registered handler without any errors.

**Actual Behavior:**
An `OSError` is raised with the message "BUFR save handler not installed". Similar errors occur for GRIB and HDF5 handlers.

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.

**Title:** Save Handlers for BUFR, GRIB, and HDF5 Stubs Not Recognized

**Description:**
When attempting to save images using the BUFR, GRIB, or HDF5 stub plugins, an `OSError` is raised indicating that the respective save handler is not installed, even after registering a handler.

**Example Buggy Code:**
```python
class TestHandler:
    def save(self, im, fp, filename):
        pass

BufrStubImagePlugin.register_handler(TestHandler())
with Image.open(TEST_FILE) as im:
    im.save("temp.bufr")
```

**Expected Behavior:**
The image should be successfully saved using the registered handler without any errors.

**Actual Behavior:**
An `OSError` is raised with the message "BUFR save handler not installed". Similar errors occur for GRIB and HDF5 handlers.
