lifecycle warning from as_tibble.matrix()

[nlichti]

Hi - I just discovered your packages, and expect them to save me a huge amount of work. Thank you for building them.

It's not really a problem, but I got the following warning from request_chebi_compound():

> names(massdatabase::request_chebi_compound())
[1] "main"                 "base_info"            "source"               "roles_classification" "iupac_name"           "synonyms"            
[7] "manual_xrefs"         "registry_numbers"    
Warning message:
The `x` argument of `as_tibble.matrix()` must have unique column names if `.name_repair` is omitted as of tibble 2.0.0.
ℹ Using compatibility `.name_repair`.
ℹ The deprecated feature was likely used in the massdatabase package.
