`.clean_names()` should replace `@` with `_`

[GegznaV]

Brief Description

Consider the following example in which @ symbol is not converted into _ in Column@Three:

import pandas as pd
import janitor

df = pd.DataFrame({
    'Column One': [1, 2, 3],
    'Column-Two': [4, 5, 6],
    'Column@Three': [7, 8, 9],
})

df_cleaned = df.clean_names()
print(df_cleaned)
#>    column_one  column_two  column@three
#> 0           1           4             7
#> 1           2           5             8
#> 2           3           6             9

.clean_names() should replace @ with _ as it does in R:

janitor::make_clean_names("Column@Tree")
#> [1] "column_tree"

@GegznaV thanks for raising this issue. Would you be open to raising a PR for this?

[deltahedge1]

is this repo part of hacktoberfest? would like to try and tackle this one as part of that event

[ericmjl]

@deltahedge1 we can make it part of Hacktoberfest! I'll tag this as part of hacktoberfest, I think that should make the repo eligible, right?

[deltahedge1]

perfect! let me take a look at this one. Thanks for adding the tag. full disclosure I am unsure if adding the tag makes it part of the event but one way to find out

[ericmjl]

@deltahedge1 let's see if that works! If you do need me to vouch for your PR, then you can send the Hacktoberfest organizers my way.
