add error filtering to map and filter

[CodyKochmann]

currently this is a thing

.filter(
  attempt(
    lambda i: i['LAST_UPD'] > datetime.date(2019, 7, 1),
    False
  )
)

and

.filter(
  attempt(
    lambda i: i['LAST_UPD'] > datetime.date(2019, 7, 1),
    default_output=False
  )
)

however

.filter(
  lambda i: i['LAST_UPD'] > datetime.date(2019, 7, 1),
  skip_errors=True
)

feels a lot nicer and is easier to remember

.filter(
  lambda i: i['LAST_UPD'] > datetime.date(2019, 7, 1),
  errors=False
)

is really clean too
