Moving `DecodeSegement` to `Parser` ( #278 )

* Moving `DecodeSegement` to `Parser`
This would allow us to remove some global variables and move them to parser options as well as potentially introduce interfaces for json and b64 encoding/decoding to replace the std lib, if someone wanted to do that for performance reasons.
We keep the functions exported because of explicit user demand.
* Sign/Verify does take the decoded form now

Allow strict base64 decoding ( #259 )
...
By default base64 decoder works in non-strict mode which
allows tweaking signatures having padding without failing validation.
This creates a potential problem if application treats token value as an identifier.
For example ES256 signature has length of 64 bytes and two padding symbols (stripped by default).
Therefore its base64-encoded value can only end with A, Q, g and w.
In non-strict mode last symbol could be tweaked resulting in 16 distinct
token values having the same signature and passing validation.
This change adds backward-compatible global config variable DecodeStrict
(similar to existing DecodePaddingAllowed) that enables strict base64 decoder mode.

Allocation optimization ( #33 )
...
* Test to ensure ECDSA signature is valid
Add assertions to ensure ECDSA signing methods return valid signatures.
This is probably covered elsewhere as well, but putting it in
ecdsa_test.go makes it more obvious and easier to find.
* Benchmark ECDSA signing methods
Add benchmark coverage of ECDSA signing methods.
Benchmarks are run using the existing helper for comparability with
existing benchmarks.
Sign method is also tested directly, to avoid the overhead of *Token.
Report allocations for all benchmarks.
Allocation count for ES384 and ES512 fluctuate across test runs,
other signing methods consistently report the same number of allocations.
Sample output:
```
$ go test -bench=Bench -run=NONE .

* Reduce allocations during ECDSA signing
Reduce the number of byte arrays allocated by using big.Int.FillBytes
when calculating ECDSA signature.
After this change, Benchmarks of ES256 signing method consistently
report 4 fewer allocations.

```
* Use base64.RawURLEncoding to avoid padding
JWT uses a non-padded base64 encoding.
Current code uses base64.URLEncoding to generate a padded string and
then removes the padding.
Likewise, current code adds padding before decoding.
Instead, use base64.RawURLEncoding which does not add or require the
padding in the first place.
In addition to making the code cleaner, this reduces memory allocations
as reported by benchmarks.

allocations are not consistent.
