> Using from_pandas to convert decimals fails if encounters a value of {{None}}. For example:
> {code:java}
> In [1]: import pyarrow as pa
> ...: import pandas as pd
> ...: from decimal import Decimal
> ...:
> In [2]: s_dec = pd.Series([Decimal('3.14'), None])
> In [3]: pa.Array.from_pandas(s_dec, type=pa.decimal128(3, 2))
> ---------------------------------------------------------------------------
> ArrowInvalid Traceback (most recent call last)
> <ipython-input-3-2da56007a0da> in <module>()
> ----> 1 pa.Array.from_pandas(s_dec, type=pa.decimal128(3, 2))
> array.pxi in pyarrow.lib.Array.from_pandas()
> array.pxi in pyarrow.lib.array()
> error.pxi in pyarrow.lib.check_status()
> error.pxi in pyarrow.lib.check_status()
> ArrowInvalid: Error converting from Python objects to Decimal: Got Python object of type NoneType but can only handle these types: decimal.Decimal
> {code}
> The above error is raised when specifying decimal type. When no type is specified, a seg fault happens.
> This previously worked in 0.8.0.
