Additional newlines added in YAML blocks for multi-line strings
Hello!

I've observed that `_extract_yaml_block()` performs `"\n".join(raw_yaml)` without having stripped the newline character in each possible line, resulting in unwanted empty lines when parsing multi-line strings in YAML blocks.

I'll give an example. With this file:

```python
#!/usr/bin/python3

import tap.parser

tap_input = """TAP version 13
1..2
ok 1 A passing test
   ---
   message: test
   severity: fail
   output: |+
     this is a multiline
     string but with tap
     somehow blank lines
     are added to it.
"""
parser = tap.parser.Parser()

for i, l in enumerate(parser.parse_text(tap_input)):
    if i == 2:
        print("{!r}".format(l.yaml_block["output"].splitlines()))
```

The output is:

```
['', 'this is a multiline', '', 'string but with tap', '', 'somehow blank lines', '', 'are added to it.']
```

Where as I expected:

```
['this is a multiline', 'string but with tap', 'somehow blank lines', 'are added to it.']
```

I will submit a PR shortly.
