Using compartments to input CSVs with custom names

I'm using CellProfiler to create Nuclei, Cells and Cytoplasm profiles, but I created each of these three CSVs using different CellProfiler methods. For example I have CSVs names Nuclei_Cellpose3, Cells_Cellpose3 and Cytoplasm_Cellpose3. I was able to run the cytotable `convert()` method for the Nuclei.csv, Cells.csv and Cytoplasm.csv and it outputted the expected parquet, I used this code snippet

```
convert(
source_path=source_path,
source_datatype="csv",
dest_path="cytotable",
dest_datatype="parquet",
concat=True,
preset="cellprofiler_csv",
no_sign_request=True,
)

```
In order to do the same for Nuclei_Cellpose3.csv, Cells_Cellpose3.csv and Cytoplasm_Cellpose3.csv, I wrote the following snippet
```
convert(
source_path=source_path,
source_datatype="csv",
dest_path="cytotable_cellpose",
dest_datatype="parquet",
compartments=["Nuclei_Cellpose3", "Cells_Cellpose3", "Cytoplasm_Cellpose3"],
join=True,
joins="ImageNumber,ObjectNumber",
page_keys={
'join': 'ImageNumber',
'Cells_Cellpose3': 'ObjectNumber',
'Nuclei_Cellpose3': 'ObjectNumber',
'Cytoplasm_Cellpose3': 'ObjectNumber'
},
preset=None
)
```
but I get this error
```
CytoTableException: No matching key found in page_keys for source_group_name: all_files.csv. Please include a pagination key based on a column name from the table.

```

Then I tried adding a key for all_files.csv by modifying the code above, and it threw an SQL error, so I changed the `join` value as follows":
```
convert(
source_path=source_path,
source_datatype="csv",
dest_path="cytotable_cellpose",
dest_datatype="parquet",
compartments=["Nuclei_Cellpose3", "Cells_Cellpose3","Cytoplasm_Cellpose3"],
join=True,
joins="ImageNumber,ObjectNumber",
page_keys={
'image': 'ImageNumber',
'Cells_Cellpose3': 'ObjectNumber',
'Nuclei_Cellpose3': 'ObjectNumber',
'Cytoplasm_Cellpose3': 'ObjectNumber',
'join': 'Cytoplasm_Number_Object_Number',
'all_files.csv': 'ImageNumber'
},
chunk_size = 10000,
sort_output=True,
preset=None
)
```
This time the code run without error but never finishes and does not create any file (tried running for 1hr, while default took 3m)

Start by reproducing the two convert() calls with the custom compartment names and compare them with the working cellprofiler_csv preset call. Trace how compartments, joins, and page_keys handle source_group_name values such as all_files.csv, then verify that a corrected invocation completes and writes the expected parquet output.
