Update ruby-roo to 2.5.1.

## [2.5.1] 2016-08-26
### Fixed
- Fixed NameError. [337](roo-rb/roo#337)

## [2.5.0] 2016-08-21
### Fixed
- Remove tempdirs via finalizers on garbage collection. This cleans them up in all known cases, rather than just when the #close method is called. The #close method can be used to cleanup early. [329](roo-rb/roo#329)
- Fixed README.md typo [318](roo-rb/roo#318)
- Parse sheets in ODS files once to improve performance [320](roo-rb/roo#320)
- Fix some Cell conversion issues [324](roo-rb/roo#324) and [331](roo-rb/roo#331)
- Improved memory performance [332](roo-rb/roo#332)
- Added `no_hyperlinks` option to improve streamig performance [319](roo-rb/roo#319) and [333](roo-rb/roo#333)

### Deprecations
- Roo::Base::TEMP_PREFIX should be accessed via Roo::TEMP_PREFIX
- The private Roo::Base#make_tempdir is now available at the class level in
  classes that use tempdirs, added via Roo::Tempdir
=======
### Added
- Discard hiperlinks lookups to allow streaming parsing without loading whole files

## [2.4.0] 2016-05-14
### Fixed
- Fixed opening spreadsheets with charts [315](roo-rb/roo#315)
- Fixed memory issues for Roo::Utils.number_to_letter [308](roo-rb/roo#308)
- Fixed Roo::Excelx::Cell::Number to recognize floating point numbers [306](roo-rb/roo#306)
- Fixed version number in Readme.md [304](roo-rb/roo#304)

### Added
- Added initial support for HTML formatting [278](roo-rb/roo#278)
