It would be convenient to choose other suffixes in DataFrame.compare than self, other

Describe the solution you'd like

Add argument suffixes so users can specify them.

API breaking implications

None

Additional context

df = pd.DataFrame(
    {"col1": ["a", "b", "c"], "col2": [1.0, 2.0, np.nan], "col3": [1.0, 2.0, 3.0]},
    columns=["col1", "col2", "col3"],
)
df2 = df.copy()
df2.loc[0, "col1"] = "c"
df2.loc[2, "col3"] = np.nan
diff = df.compare(df2, suffixes=["left", "right"])
print(diff)

  col1       col3      
  left right left right
0    a     c  NaN   NaN
2  NaN   NaN  3.0   NaN

seems reasonable

In the source code, suffixes is fixed to keys=['self', 'other'], change the value of keys to the value of suffixes transferred by the user.
