Skip GetSignedArea.ErrorAccumulation test on macOS (#407)

This was previously skipped only for AArch64 macOS.

https://github.com/google/s2geometry/blob/master/src/s2/s2loop_measures_test.cc#L256

The test fails for x86-64 macOS as well.  

#395 (comment)

Disable for __APPLE__.

Bump version to 0.11.1

Bump version to 0.11.0

Prepare for 0.11.0 release.

Fix error: use of undeclared identifier 'ABSL_INTERNAL_ASSUME' (#238)

`ABSL_INTERNAL_ASSUME` was replaced by `ABSL_ASSUME` in
abseil/abseil-cpp@231c393.

Define `S2_ASSUME` to either `ABSL_ASSUME` or `ABSL_INTERNAL_ASSUME`, depending on what's available. The latest LTS release does not yet have `S2_ASSUME`.

Fixes #237

Merge pull request #230 from jmr/update-2022-02-17

Update to latest google3 version

* Remove deprecated s2textformat functions (where ...OrDie should be
  used instead)
* Use absl::make_unique instead of raw new in some places
* Add missing includes
* Deprecate many functions taking const pointers; change to const
  references
* Deprecate InterpolateAtDistance (use GetPointOnLine instead)

Bits: Remove use of FRIEND_TEST and gunit_prod

We don't include the Bits tests, so these are pointless
and pollute the public API with gtest, even if gtest
was not configured.

Revert "Use cstdint types in integral_types.h"

This reverts commit 101ae83.

This unbreaks pywraps2_test in Travis CI's configuration.

  Possible C/C++ prototypes are:

    S2CellId::S2CellId(S2Point const &)
    S2CellId::S2CellId(S2LatLng const &)
    S2CellId::S2CellId()

Possibly related to different SWIG or stdint.i versions.  It looks like
the uint64 -> uint64_t mapping is not being found.

It worked when I tested.
