Exclude more non-local numbers from geocoding in Finland

Per http://www.viestintavirasto.fi/attachments/maaraykset/Regulation_32.pdf
(official numbering plan), in Finland (+358):

- 020*: Nationwide service and subscriber numbers
- 029*: Nationwide subscriber numbers
- 030*: Nationwide service and subscriber numbers
- 039*: Nationwide subscriber numbers
- 060*: Nationwide service numbers
- 0800*: Nationwide toll-free service numbers

"Nationwide" numbers are non-geographic as per Chapter 2 Section 6.

The local subscriber numbers starting with 02,03,06,08,09 have 1..8 as
their third number.

However, libphonenumber assigns 02*, 03*, 06* and 08* to specific
locations in their entirety, causing e.g. some nationwide service numbers
to be incorrectly geocoded. 09* is also geocoded in its entirety, even
though 090* and 099* are reserved and may get later assigned to
nationwide numbers like in the other number series.

Instead of using catch-all geocoding for 02,03,06,08,09, add the actually
local subscriber telephone number allocations 0X[1-8] separately.
