Add support for private fields (by not emitting them) #13
Description
If a field is marked private I think it'd be nice if they weren't emitted at all.
Right now it seems marking them as such via e.g.:
--- An individual pin.
---@class Pin
---@field id string @a label to identify the pin
---@field private __data_element Element
---@field private __element Element
---@field private __extmark number
---@field private __extmark_buf number
is misparsed as the field name:
Pin *Pin*
Fields: ~
{id} (string) @a label to identify the pin
{private} (__data_element) Element
{private} (__element) Element
{private} (__extmark) number
{private} (__extmark_buf) number
