Unable to parse column in cast/try_cast with function

[chezou]

When cast or try_cast has column in function, it won't be parsed.

Actual

$ sqllineage -l column -e "insert overwrite table tbl1 select try_cast(coalesce(col2, 0) as varchar) AS col1 from t1"
<default>.tbl1.col1 <- <default>.t1.coalesce

Expected

sqllineage -l column -e "insert overwrite table tbl1 select try_cast(coalesce(col2, 0) as varchar) AS col1 from t1"
<default>.tbl1.col1 <- <default>.t1.col2

try_cast is something new to me, thanks for your input. We definitely need to improve on this part.
