Tensor shape checks inspired by einstein notation

## Overview

This library has three main functions:

* `check_shapes` takes tuples of `(Tensor, shape)` and checks that all the Tensors match the shapes

```

check_shapes((x, "i 3"), (y, "i 3"))

```

* `check_func` is a function decorator to check the input and output shapes of a function

```

@check_func("*i x, *i y -> *i (x + y)")

def concat(a, b):

    return np.concatenate([a, b], -1)

```

* `check_data` is a class decorator to check the fields of a data class

```

@check_data(start="i 2", end="i 2")

class LineSegment2D(NamedTuple):

    start: torch.Tensor

    end: torch.Tensor

```
